60-420: Vladimir Arutyunian ( Georgian : ვლადიმერ არუთინიანი Vladimer Arutiniani ; Armenian : Վլադիմիր Հարությունյան , romanized :  Vladimir Harut’yunyan ; born 12 March 1978) is a Georgian national who, on 10 May 2005, attempted to assassinate United States President George W. Bush and Georgian President Mikheil Saakashvili by throwing a hand grenade at both of them. The attempt failed when

120-434: A hydrogen-based economy . It is an alternative to electrolysis , and does not require hydrocarbons like current methods of steam reforming . But note that all of the available energy in the hydrogen so produced is supplied by the heat used to make it. Sulfuric acid is rarely encountered naturally on Earth in anhydrous form, due to its great affinity for water . Dilute sulfuric acid is a constituent of acid rain , which

180-551: A presidential pardon , but such pardons are almost never granted in Georgia. Georgian language Georgian is most closely related to the Zan languages ( Megrelian and Laz ) and more distantly to Svan . Georgian has various dialects , with standard Georgian based on the Kartlian dialect, and all dialects are mutually intelligible. The history of Georgian spans from Early Old Georgian in

240-451: A vigesimal numeric system like Basque and (partially) French . Numbers greater than 20 and less than 100 are described as the sum of the greatest possible multiple of 20 plus the remainder. For example, "93" literally translates as 'four times twenty plus thirteen' ( ოთხმოცდაცამეტი , otkhmotsdatsamet’i ). One of the most important Georgian dictionaries is the Explanatory dictionary of

300-552: A Roman grammarian from the 2nd century AD. The first direct attestations of the language are inscriptions and palimpsests dating to the 5th century, and the oldest surviving literary work is the 5th century Martyrdom of the Holy Queen Shushanik by Iakob Tsurtaveli . The emergence of Georgian as a written language appears to have been the result of the Christianization of Georgia in the mid-4th century, which led to

360-610: A base and can be protonated, forming the [H 3 SO 4 ] ion. Salts of [H 3 SO 4 ] have been prepared (e.g. trihydroxyoxosulfonium hexafluoroantimonate(V) [H 3 SO 4 ] [SbF 6 ] ) using the following reaction in liquid HF : The above reaction is thermodynamically favored due to the high bond enthalpy of the Si–F bond in the side product. Protonation using simply fluoroantimonic acid , however, has met with failure, as pure sulfuric acid undergoes self-ionization to give [H 3 O] ions: which prevents

420-408: A burnt appearance in which the carbon appears much like soot that results from fire. Although less dramatic, the action of the acid on cotton , even in diluted form, destroys the fabric. The reaction with copper(II) sulfate can also demonstrate the dehydration property of sulfuric acid. The blue crystals change into white powder as water is removed. Sulfuric acid reacts with most bases to give

480-665: A capital-like effect called Mtavruli for titles and inscriptions. Georgian is an agglutinative language with a complex verb structure that can include up to eight morphemes , exhibiting polypersonalism . The language has seven noun cases and employs a left-branching structure with adjectives preceding nouns and postpositions instead of prepositions. Georgian lacks grammatical gender and articles, with definite meanings established through context. Georgian's rich derivation system allows for extensive noun and verb formation from roots, with many words featuring initial consonant clusters. The Georgian writing system has evolved from ancient scripts to

540-411: A dehydrating agent, forming the nitronium ion NO + 2 , which is important in nitration reactions involving electrophilic aromatic substitution . This type of reaction, where protonation occurs on an oxygen atom, is important in many organic chemistry reactions, such as Fischer esterification and dehydration of alcohols. When allowed to react with superacids , sulfuric acid can act as

600-490: A ri means 'friend'; megobrebi ( megob Ø rebi ) means 'friends', with the loss of a in the last syllable of the word stem. Georgian has seven noun cases: nominative , ergative , dative , genitive , instrumental , adverbial and vocative . An interesting feature of Georgian is that, while the subject of a sentence is generally in the nominative case and the object is in the accusative case (or dative), one can find this reversed in many situations (this depends mainly on

660-399: A row, as may be seen in words like გვფრცქვნ ი gvprtskvni 'you peel us' and მწვრთნ ელი mts’vrtneli 'trainer'. Vicenik has observed that Georgian vowels following ejective stops have creaky voice and suggests this may be one cue distinguishing ejectives from their aspirated and voiced counterparts. Georgian has been written in a variety of scripts over its history. Currently

720-487: A slower rate, so that the acid neutralizing capacity (ANC) of the aquifer can neutralize the produced acid. In such cases, the total dissolved solids (TDS) concentration of the water can be increased from the dissolution of minerals from the acid-neutralization reaction with the minerals. Sulfuric acid is used as a defense by certain marine species, for example, the phaeophyte alga Desmarestia munda (order Desmarestiales ) concentrates sulfuric acid in cell vacuoles. In

780-544: A terrorist, I'm just a human being. After his arrest, Arutyunian was shown on television admitting from his hospital bed that he had thrown the grenade. He said that he had attempted to assassinate both presidents because he hated Georgia's new government for being a "puppet" of the United States. He further stated that he did not regret what he did and would do it again if he had the chance. Arutyunian initially admitted his guilt when arrested but refused to cooperate during

840-484: A tip from a hotline, police raided Arutyunian's home where he lived with his mother. During an ensuing gunfight, Arutyunian killed the head of the Interior Ministry's counterintelligence department, Zurab Kvlividze. He then fled into the woods in the village of Vashlijvari on the outskirts of Tbilisi . After being wounded in the leg, he was captured by Georgia's anti-terror unit. DNA samples from Arutyunian matched

900-510: A vapor pressure of <1 mmHg at 40 °C. In the solid state, sulfuric acid is a molecular solid that forms monoclinic crystals with nearly trigonal lattice parameters. The structure consists of layers parallel to the (010) plane, in which each molecule is connected by hydrogen bonds to two others. Hydrates H 2 SO 4 · n H 2 O are known for n = 1, 2, 3, 4, 6.5, and 8, although most intermediate hydrates are stable against disproportionation . Anhydrous H 2 SO 4

960-589: A word. Georgian vowels in non-initial syllables are pronounced with a shorter duration compared to vowels in initial syllables. long polysyllabic words may have a secondary stress on their third or fourth syllable. Georgian contains many "harmonic clusters" involving two consonants of a similar type (voiced, aspirated, or ejective) that are pronounced with only a single release; e.g. ბგ ერა bgera 'sound', ცხ ოვრება tskhovreba 'life', and წყ ალი ts’q’ali 'water'. There are also frequent consonant clusters , sometimes involving more than six consonants in

1020-442: Is a common laboratory demonstration. The sugar darkens as carbon is formed, and a rigid column of black, porous carbon called a carbon snake may emerge. Similarly, mixing starch into concentrated sulfuric acid gives elemental carbon and water. The effect of this can also be seen when concentrated sulfuric acid is spilled on paper. Paper is composed of cellulose , a polysaccharide related to starch. The cellulose reacts to give

1080-556: Is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide . Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus, the reverse procedure of adding water to the acid is generally avoided since the heat released may boil the solution, spraying droplets of hot acid during the process. Upon contact with body tissue, sulfuric acid can cause severe acidic chemical burns and secondary thermal burns due to dehydration. Dilute sulfuric acid

1140-484: Is a strong acid: The product of this ionization is HSO − 4 , the bisulfate anion. Bisulfate is a far weaker acid: The product of this second dissociation is SO 2− 4 , the sulfate anion. Concentrated sulfuric acid has a powerful dehydrating property, removing water ( H 2 O ) from other chemical compounds such as table sugar ( sucrose ) and other carbohydrates , to produce carbon , steam , and heat. Dehydration of table sugar (sucrose)

1200-429: Is a very polar liquid, having a dielectric constant of around 100. It has a high electrical conductivity , a consequence of autoprotolysis , i.e. self- protonation  : The equilibrium constant for autoprotolysis (25 °C) is: The corresponding equilibrium constant for water , K w is 10 , a factor of 10 (10 billion) smaller. In spite of the viscosity of the acid, the effective conductivities of

1260-547: Is also a key substance in the chemical industry . It is most commonly used in fertilizer manufacture but is also important in mineral processing , oil refining , wastewater processing , and chemical synthesis . It has a wide range of end applications, including in domestic acidic drain cleaners , as an electrolyte in lead-acid batteries , as a dehydrating compound, and in various cleaning agents . Sulfuric acid can be obtained by dissolving sulfur trioxide in water. Although nearly 100% sulfuric acid solutions can be made,

1320-487: Is because syllables in the language often begin with two consonants. Recordings are available on the relevant Wiktionary entries, linked to below. Article 1 of the Universal Declaration of Human Rights : Sulfuric acid Sulfuric acid ( American spelling and the preferred IUPAC name ) or sulphuric acid ( Commonwealth spelling ), known in antiquity as oil of vitriol , is a mineral acid composed of

1380-499: Is called acid mine drainage (AMD) or acid rock drainage (ARD). The Fe can be further oxidized to Fe : The Fe produced can be precipitated as the hydroxide or hydrous iron oxide : The iron(III) ion ("ferric iron") can also oxidize pyrite: When iron(III) oxidation of pyrite occurs, the process can become rapid. pH values below zero have been measured in ARD produced by this process. ARD can also produce sulfuric acid at

1440-402: Is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e. oxidation of sulfurous acid . When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief products carbon oxides and water). Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as pyrite : The resulting highly acidic water

1500-493: Is prepared by slowly adding 98% sulfuric acid to an equal volume of water, with good stirring: the temperature of the mixture can rise to 80 °C (176 °F) or higher. Sulfuric acid contains not only H 2 SO 4 molecules, but is actually an equilibrium of many other chemical species, as it is shown in the table below. Sulfuric acid is a colorless oily liquid, and has a vapor pressure of <0.001 mmHg at 25 °C and 1 mmHg at 145.8 °C, and 98% sulfuric acid has

1560-998: Is rather light, and in fact Georgian transliterates the tenuis stops in foreign words and names with the ejectives. The coronal occlusives ( /tʰ tʼ d n/ , not necessarily affricates) are variously described as apical dental, laminal alveolar, and "dental". Per Canepari, the main realizations of the vowels are [ i ], [ e̞ ], [ ä ], [ o̞ ], [ u ]. Aronson describes their realizations as [ i̞ ], [ e̞ ], [ ä ] (but "slightly fronted"), [ o̞ ], [ u̞ ]. Shosted transcribed one speaker's pronunciation more-or-less consistently with [ i ], [ ɛ ], [ ɑ ], [ ɔ ], [ u ]. Allophonically, [ ə ] may be inserted to break up consonant clusters, as in /dɡas/ [dəɡäs] . In casual speech, /iV, Vi/ sequences can be realized phonetically as [jV~i̯V, Vj~Vi̯]. Phrase-final unstressed vowels may sometimes be partially reduced. Prosody in Georgian involves stress, intonation, and rhythm. Stress

1620-428: Is substantially less hazardous without the oxidative and dehydrating properties; though, it is handled with care for its acidity. Sulfuric acid is a very important commodity chemical; a country's sulfuric acid production is a good indicator of its industrial strength. Many methods for its production are known, including the contact process , the wet sulfuric acid process , and the lead chamber process . Sulfuric acid

1680-401: Is very weak, and linguists disagree as to where stress occurs in words. Jun, Vicenik, and Lofstedt have proposed that Georgian stress and intonation are the result of pitch accents on the first syllable of a word and near the end of a phrase. According to Borise, Georgian has fixed initial word-level stress cued primarily by greater syllable duration and intensity of the initial syllable of

1740-466: The H 3 SO + 4 and HSO − 4 ions are high due to an intramolecular proton-switch mechanism (analogous to the Grotthuss mechanism in water), making sulfuric acid a good conductor of electricity. It is also an excellent solvent for many reactions. The hydration reaction of sulfuric acid is highly exothermic , dilution. As indicated by its acid dissociation constant , sulfuric acid

1800-452: The Dittionario giorgiano e italiano . These were meant to help western Catholic missionaries learn Georgian for evangelical purposes. On the left are IPA symbols, and on the right are the corresponding letters of the modern Georgian alphabet, which is essentially phonemic. Former /qʰ/ ( ჴ ) has merged with /x/ ( ხ ), leaving only the latter. The glottalization of the ejectives

1860-494: The Mkhedruli script is almost completely dominant; the others are used mostly in religious documents and architecture. Mkhedruli has 33 letters in common use; a half dozen more are obsolete in Georgian, though still used in other alphabets, like Mingrelian, Laz, and Svan. The letters of Mkhedruli correspond closely to the phonemes of the Georgian language. According to the traditional account written down by Leonti Mroveli in

1920-686: The Democratic Union for Revival party led by Aslan Abashidze in January 2004, but soon after left the organization's ranks. He joined the Revival party in the same month Mikheil Saakashvili became president of Georgia and had led Adjara in a crisis by refusing to obey the central government authorities. Saakashvili and his party were considered to be pro-United States, while Abashidze and his party were considered to be pro-Russia. The crisis ended in 2004 without bloodshed. On 10 May 2005, Arutyunian waited for

1980-506: The Georgian Orthodox Church and together are called Khutsuri 'priest alphabet'. In Mkhedruli , there is no case. Sometimes, however, a capital-like effect, called Mtavruli ('title' or 'heading'), is achieved by modifying the letters so that their vertical sizes are identical and they rest on the baseline with no descenders. These capital-like letters are often used in page headings, chapter titles, monumental inscriptions, and

2040-452: The Kartlian dialect. Over the centuries, it has exerted a strong influence on the other dialects. As a result, they are all, generally, mutually intelligible with standard Georgian, and with one another. The history of the Georgian language is conventionally divided into the following phases: The earliest extant references to Georgian are found in the writings of Marcus Cornelius Fronto ,

2100-448: The stratosphere , the atmosphere's second layer that is generally between 10 and 50 km above Earth's surface, sulfuric acid is formed by the oxidation of volcanic sulfur dioxide by the hydroxyl radical : Because sulfuric acid reaches supersaturation in the stratosphere, it can nucleate aerosol particles and provide a surface for aerosol growth via condensation and coagulation with other water-sulfuric acid aerosols. This results in

2160-418: The stratospheric aerosol layer . The permanent Venusian clouds produce a concentrated acid rain, as the clouds in the atmosphere of Earth produce water rain. Jupiter 's moon Europa is also thought to have an atmosphere containing sulfuric acid hydrates. Sulfuric acid is produced from sulfur , oxygen and water via the conventional contact process (DCDA) or the wet sulfuric acid process (WSA). In

2220-452: The 11th century, the first Georgian script was created by the first ruler of the Kingdom of Iberia , Pharnavaz , in the 3rd century BC. The first examples of a Georgian script date from the 5th century AD. There are now three Georgian scripts, called Asomtavruli 'capitals', Nuskhuri 'small letters', and Mkhedruli . The first two are used together as upper and lower case in the writings of

2280-677: The 5th century, to Modern Georgian today. Its development as a written language began with the Christianization of Georgia in the 4th century. Georgian phonology features a rich consonant system, including aspirated, voiced, and ejective stops , affricates , and fricatives . Its vowel system consists of five vowels with varying realizations. Georgian prosody involves weak stress, with disagreements among linguists on its placement. The language's phonotactics include complex consonant clusters and harmonic clusters. The Mkhedruli script , dominant in modern usage, corresponds closely to Georgian phonemes and has no case distinction, though it employs

2340-450: The DNA samples from the handkerchief. Georgian police later found a chemical lab and a stockpile of explosives, chemicals and other material Arutyunian had built up in his apartment. Twenty liters (5.3 U.S. gallons) of sulfuric acid , several drawers full of mercury thermometers, a microscope, and "enough dangerous substances to carry out several terrorist acts" were found. I don't consider myself

2400-568: The Georgian language ( ქართული ენის განმარტებითი ლექსიკონი ). It consists of eight volumes and about 115,000 words. It was produced between 1950 and 1964, by a team of linguists under the direction of Arnold Chikobava . Georgian has a word derivation system, which allows the derivation of nouns from verb roots both with prefixes and suffixes, for example: It is also possible to derive verbs from nouns: Likewise, verbs can be derived from adjectives, for example: In Georgian many nouns and adjectives begin with two or more contiguous consonants. This

2460-530: The US Federal Bureau of Investigation began an investigation into the incident. Extra manpower was brought in from the surrounding region to help with the investigation. In one picture of the crowd, the FBI noted a man in the bleachers with a large camera. He was a visiting professor from Boise , Idaho . FBI agents contacted him and, with his photographs, were able to identify a suspect. On 20 July 2005, acting on

2520-669: The United States President George W. Bush and Georgian President Mikheil Saakashvili to speak in Tbilisi's central Liberty Square . When Bush began speaking, Arutyunian threw a Soviet-made RGD-5 hand grenade, wrapped in a red tartan handkerchief, toward the podium where Bush stood as he addressed the crowd. The grenade landed 18.6 metres (61 ft) from the podium, near where Saakashvili, his wife Sandra Roelofs , Laura Bush , and other officials were seated. The grenade failed to detonate. Although original reports indicated that

2580-498: The acid produced in the lead chamber itself (<70% to avoid contamination with nitrosylsulfuric acid ) and tower acid being the acid recovered from the bottom of the Glover tower. They are now obsolete as commercial concentrations of sulfuric acid, although they may be prepared in the laboratory from concentrated sulfuric acid if needed. In particular, "10 M" sulfuric acid (the modern equivalent of chamber acid, used in many titrations ),

2640-403: The character of the verb). This is called the dative construction . In the past tense of the transitive verbs, and in the present tense of the verb "to know", the subject is in the ergative case. Georgian has a rich word-derivation system. By using a root, and adding some definite prefixes and suffixes, one can derive many nouns and adjectives from the root. For example, from the root - kart -,

2700-423: The cloth matched Arutyunian's. On 11 January 2006, a Georgian court sentenced Arutyunian to life imprisonment for the attempted assassination of George Bush and Mikheil Saakashvili, and the killing of Officer Kvlividze. In September 2005, a United States federal grand jury also indicted Arutyunian, and could ask to extradite him if he is ever released. He is not eligible for parole, and could only be released under

2760-837: The conversion of H 2 SO 4 to [H 3 SO 4 ] by the HF/ SbF 5 system. Even dilute sulfuric acid reacts with many metals via a single displacement reaction, like other typical acids , producing hydrogen gas and salts (the metal sulfate). It attacks reactive metals (metals at positions above copper in the reactivity series ) such as iron , aluminium , zinc , manganese , magnesium , and nickel . Concentrated sulfuric acid can serve as an oxidizing agent , releasing sulfur dioxide: Lead and tungsten , however, are resistant to sulfuric acid. Hot concentrated sulfuric acid oxidizes carbon (as bituminous coal ) and sulfur : Benzene and many derivatives undergo electrophilic aromatic substitution with sulfuric acid to give

2820-412: The corresponding sulfonic acids : Sulfuric acid can be used to produce hydrogen from water : The compounds of sulfur and iodine are recovered and reused, hence the process is called the sulfur–iodine cycle . This process is endothermic and must occur at high temperatures, so energy in the form of heat has to be supplied. The sulfur–iodine cycle has been proposed as a way to supply hydrogen for

2880-606: The corresponding sulfate or bisulfate. Sulfuric acid reacts with sodium chloride , and gives hydrogen chloride gas and sodium bisulfate : Aluminium sulfate , also known as paper maker's alum, is made by treating bauxite with sulfuric acid: Sulfuric acid can also be used to displace weaker acids from their salts. Reaction with sodium acetate , for example, displaces acetic acid , CH 3 COOH , and forms sodium bisulfate : Similarly, treating potassium nitrate with sulfuric acid produces nitric acid . When combined with nitric acid , sulfuric acid acts both as an acid and

2940-452: The current Mkhedruli, used for most purposes. The language has a robust grammatical framework with unique features such as syncope in morphophonology and a left-branching syntax. Georgian's vocabulary is highly derivational, allowing for diverse word formations, while its numeric system is vigesimal. No claimed genetic links between the Kartvelian languages and any other language family in

3000-520: The elements sulfur , oxygen , and hydrogen , with the molecular formula H 2 SO 4 . It is a colorless, odorless, and viscous liquid that is soluble with water. Pure sulfuric acid does not occur naturally due to its strong affinity to water vapor ; it is hygroscopic and readily absorbs water vapor from the air . Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide

3060-498: The following words can be derived: Kart veli ('a Georgian person'), Kart uli ('the Georgian language') and Sa kart velo ('the country of Georgia'). Most Georgian surnames end in - dze 'son' (Western Georgia), - shvili 'child' (Eastern Georgia), - ia (Western Georgia, Samegrelo ), - ani (Western Georgia, Svaneti ), - uri (Eastern Georgia), etc. The ending - eli is a particle of nobility, comparable to French de , Dutch van , German von or Polish - ski . Georgian has

3120-617: The grenade did not detonate. He was later arrested and sentenced to life in prison . Vladimir Arutyunian, a Georgian citizen and ethnic Armenian , was born on 12 March 1978 in Tbilisi , Soviet Georgia . Arutyunian lost his father at an early age and lived with his mother, who was a stall-holder at the local street market. After the collapse of the Soviet Union, they lived in one of the poorest suburbs of Tbilisi. After completing his secondary education, he had no fixed occupation. Arutyunian joined

3180-406: The grenade was not live, it was later revealed that it was. After Arutyunian pulled the pin and threw the grenade, it hit a girl, cushioning its impact. The red handkerchief remained wrapped around the grenade, and it prevented the striker lever from releasing. A Georgian security officer quickly removed the grenade, and Arutyunian disappeared. Arutyunian later said that he threw the grenade "towards

3240-412: The heads" so that "the shrapnel would fly behind the bulletproof glass". Bush and Saakashvili did not learn of the incident until after the rally. On 18 July 2005, Georgia's Interior Minister Vano Merabishvili issued photos of an unidentified suspect and announced a reward of 150,000 lari (US$ 80,000) for information leading to the suspect's identification. At the request of the Georgian government,

3300-498: The like. This is the Georgian standard keyboard layout. The standard Windows keyboard is essentially that of manual typewriters . Georgian is an agglutinative language . Certain prefixes and suffixes can be joined in order to build a verb. In some cases, one verb can have up to eight different morphemes in it at the same time. An example is ageshenebinat ('you [all] should've built [it]'). The verb can be broken down to parts: a-g-e-shen-eb-in-a-t . Each morpheme here contributes to

3360-472: The meaning of the verb tense or the person who has performed the verb. The verb conjugation also exhibits polypersonalism ; a verb may potentially include morphemes representing both the subject and the object. In Georgian morphophonology , syncope is a common phenomenon. When a suffix (especially the plural suffix - eb -) is attached to a word that has either of the vowels a or e in the last syllable, this vowel is, in most words, lost. For example, megob

3420-617: The replacement of Aramaic as the literary language . By the 11th century, Old Georgian had developed into Middle Georgian. The most famous work of this period is the epic poem The Knight in the Panther's Skin , written by Shota Rustaveli in the 12th century. In 1629, a certain Nikoloz Cholokashvili authored the first printed books written (partially) in Georgian, the Alphabetum Ibericum sive Georgianum cum Oratione and

3480-445: The subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid". Other concentrations are used for different purposes. Some common concentrations are: "Chamber acid" and "tower acid" were the two concentrations of sulfuric acid produced by the lead chamber process , chamber acid being

"I consider that everything was far from proved." She cited the fact that Arutyunian's fingerprints were not found on the grenade. However, prosecutor Anzor Khvadagiani said that the grenade being wrapped in cloth explained the lack of distinguishable fingerprints and also that DNA tests of material found on

3600-399: The world are accepted in mainstream linguistics. Among the Kartvelian languages, Georgian is most closely related to the so-called Zan languages ( Megrelian and Laz ); glottochronological studies indicate that it split from the latter approximately 2700 years ago. Svan is a more distant relative that split off much earlier, perhaps 4000 years ago. Standard Georgian is largely based on
