Ostwald remained on the faculty at Leipzig University until his retirement in 1906. He also served as the first "exchange professor" at Harvard University in 1904 and 1905. During Ostwald's academic career, he had many research students who became accomplished scientists in their own right. These included future Nobel Laureates Svante Arrhenius , Jacobus Henricus van 't Hoff , and Walther Nernst . Other students included Arthur Noyes , Willis Rodney Whitney and Kikunae Ikeda . All of these students became notable for their contributions to physical chemistry. In 1901, Albert Einstein applied for

249-420: A geologic timescale , many minerals exhibit Ostwald Ripening as their crystal forms evolve as the mineral ages. Related to solubility and crystallization was Ostwald's finding that dissolution of a solid depends on the size of the crystal. When the crystals are small, typically less than a micron , the solubility of the solid in the solution phase is increased. Ostwald quantified this effect mathematically in

332-500: A polymath . Ostwald was born ethnically Baltic German in Riga , Russian Empire (now Latvia ) to master-cooper Gottfried Wilhelm Ostwald (1824–1903) and Elisabeth Leuckel (1824–1903). He was the middle child of three, born after Eugen (1851–1932) and before Gottfried (1855–1918).

This type of pipette has a bulb at the lower end as a particular design feature. It became known as the Ostwald-Folin pipette and is widely used in contemporary times. Following his 1906 retirement from academia, Ostwald became interested in the systematization of colors , which could be useful both scientifically and in

1079-539: A relationship that became known as the Ostwald-Freundlich equation . Ostwald first published his finding in 1900, and his mathematical equation was refined by German chemist Herbert Freundlich in 1909. This mathematical relationship also applies to the partial pressure of substance in the system. The Ostwald-Freundlich equation takes into account the surface tension of the particle in the system, in addition to curvature and temperature. The size dependence of solubility

1162-473: A research position in Ostwald's laboratory. This was four years before Einstein's publication on special relativity . Ostwald rejected Einstein's application, although later the two developed strong mutual respect. Subsequently, Ostwald nominated Einstein for the Nobel Prize in 1910 and again in 1913. Following his 1906 retirement, Ostwald became active in philosophy, politics, and other humanities. During

1245-406: A solution of certain chemical reactants can have a strong influence of the rate of chemical processes. He realized that this is manifestation of the concept of chemical catalysis first articulated by Berzelius . Ostwald articulated the idea that a catalyst is a substance that accelerates the rate of a chemical reaction without being a part of either the reactants or the products. Ostwald's advances in

1328-400: A thirst for learning new things. In this way, it symbolizes knowledge and intelligence. Later on, Tiksu is said to have met an ornithologist who also gave lectures at a university.

1577-484: Is sometimes utilized in the formulation of pharmaceuticals that have low solubility so as to enhance their uptake by the patient. The size dependence also has a role in Ostwald Ripening. Collaborating with German chemist Raphael E. Liesegang , Ostwald recognized that substances can crystallize in a periodic fashion wherein the crystallization behavior follows a spatial or temporal pattern. In certain circumstances,

1660-533: The Academy of Åbo (in Turku , Finland ). A precursor to the academy had been a Jesuit grammar school Gymnasium Dorpatense , founded by Stefan Batory (then king of Poland–Lithuania ) in 1583 and existing to 1601, when Tartu (Dorpat) was under Polish–Lithuanian rule. The first students matriculated between 20 and 21 April 1632. The opening ceremony of Academia Dorpatensis (Academia Gustaviana) took place on 15 October in

This characteristic of weak electrolytes can be observed experimentally, such as by electrochemical determinations . Through his research on chemical reaction rates and velocities and his studies of acids and bases, Ostwald found that the concentration of acid or the concentration of base in

3320-401: The chemical systems under investigation. He therefore turned to physical measurements as surrogate methods to understand these important basic phenomena. One such physical measurement is the measurement of the viscosity , or resistance to flow, of a liquid. Ostwald invented a device for this purpose consisting of bulbs that act as reservoirs for a liquid with a capillary, or thin tube, in between

3403-451: The circumference or curved surfaces of the two cones. In this representation, each color is a mixture of white, black, and the eight primary colors. In this way, there are three degrees of freedom that represent each color. This representation of colors was an important early step toward their systematization, replacing color perception by the human eye with an objective system. Over time, Ostwald's advances in color science became part of

Many common materials exhibit this type of behavior, including minerals and various organic compounds . This finding came to be known as Ostwald's rule . Ostwald realized that solid or liquid solutions can continue to evolve over time. While

4897-500: The reservoirs. The time that it takes for the liquid to flow through the capillary from one reservoir to the other is an indication of the viscosity of the liquid. Using a reference solution, the viscosity of the liquid can be quantified. Ostwald typically used this device to study the behavior of solutes in water solutions. These devices came to be known as Ostwald viscometers and are in widespread use in contemporary times for research and quality control purposes. Ostwald designed

Ostwald is credited with being one of the founders of the field of physical chemistry , with Jacobus Henricus van 't Hoff , Walther Nernst , and Svante Arrhenius . He received the Nobel Prize in Chemistry in 1909 for his scientific contributions to the fields of catalysis , chemical equilibria , and reaction velocities . Following his 1906 retirement from academic life, Ostwald became much involved in philosophy, art, and politics. He made significant contributions to each of these fields. He has been described as

6059-585: Was a member of a Committee of the Delegation for the Adoption of an International Auxiliary Language . Ostwald donated half the proceedings of his 1909 Nobel prize to the Ido movement, funding the Ido magazine Progreso which he had proposed in 1908. Ostwald later went on to create his own language Weltdeutsch in a period of extreme nationalism during the First World War. One of Ostwald's continuing interests

6142-514: Was also engaged in the peace movement of Berta von Suttner . Among his other interests, Ostwald was a passionate amateur painter who made his own pigments. He left more than 1,000 paintings along with 3,000 pastels and color studies. For Ostwald, science and the arts were mutually supportive areas of engagement. "Poetry, music and painting have given me refreshment and new courage, when exhausted by scientific work I have been obliged to lay my tools aside."–Ostwald Ostwald regarded science and

6225-686: Was awarded the Wilhelm Exner Medal , which recognized the economic impact of Ostwald's scientific contributions. In 1904 he was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences . He became an honorary member of scientific societies in Germany, Sweden, Norway, the Netherlands, Russia, Great Britain, and the United States. Ostwald received honorary doctorates from various universities in Germany, Great Britain and

6308-502: Was deeply interested in questions of chemical affinity and the reactions that formed chemical compounds . This was the central theoretical question facing chemists at the time. As part of his early work, Ostwald developed a three-dimensional affinity table that took into account the effects of temperature as well as the affinity constants of acids and bases . Ostwald also investigated mass action , electrochemistry , and chemical dynamics . Ostwald completed his Magisterial degree at

6391-546: Was elected an International Honorary Member of the American Academy of Arts and Sciences in 1905 and an International Member of the United States National Academy of Sciences in 1906. He received the 1909 Nobel Prize for Chemistry for his contributions to understanding catalysis and for his investigations of the fundamental principles underlying chemical equilibria and reaction rates. He was nominated for

6474-458: Was in short supply during World War I . The process is often referred to as the Ostwald Process . The process remains in widespread use in contemporary times for manufacture of nitric acid. Ostwald also conducted significant research on dilution theory leading to his conceptualization of the law of dilution which at times is referred to as "Ostwald's Dilution Law". This theory holds that

6557-568: Was liberal, pacifist, and international, seeking in science a basis of values to support social and political reforms. Ostwald himself developed a system of ethics based on science, around the core idea that one should "not waste energy, but convert it into its most useful form." in 1911, Ostwald became President of the Deutscher Monistenbund (Monist Association), founded by Ernst Haeckel . Ostwald (and other Monists) promoted eugenics and euthanasia , but only as voluntary choices with

6640-608: Was near the theoretical limit . Aspects of the basic process had also been patented some 64 years earlier by Kuhlmann . Kuhlmann's process did not become industrially significant, likely due to the lack of an inexpensive source of ammonia. Shortly after Ostwald's finding, inexpensive ammonia became available as a result of Haber and Bosch's invention of a process for nitrogen fixing process (completed by 1911 or 1913) for ammonia synthesis. The combination of these two breakthroughs soon led to more economical and larger-scale production of fertilizers and explosives , of which Germany

6723-471: Was one of the last holdouts. He explained in a conversation with Arnold Sommerfeld that he was convinced by Jean Perrin 's experiments on Brownian motion . In 1906 Ostwald was elected a member of the International Committee on Atomic Weights . As a consequence of World War I , this membership ended in 1917 and was not resumed after the war. The 1917 Annual Report of the committee ended with

6806-503: Was thus allowed to continue in German until 1916). By 1898, when both the town and the university were renamed Yuryev, virtually all distinguished scholars from Germany had left. The University of Yuryev existed until 1918, when during part of the fall term, it was reopened, under German occupation , as Dorpat. Russian academic staff and students took refuge in Voronezh in Russia, giving rise to

6889-426: Was unification through systematization. In particular, Ostwald perceived that energy efficiency was a unifying theme in all facets of society and culture. In political matters, Ostwald's interest in energy efficiency extended to such political matters as the need for organization of labor. Ostwald's interest in unification through systematization led to his adaptation of the philosophy of Monism . Initially, Monism
