817-520: The election. Early in his career, Brønsted studied chemical thermodynamics and later studied electrolyte solutions and carried out an extensive series of solubility measurements. These measurements led him to establish general laws which were later confirmed when the Debye–Hückel theory was proposed.

1462-543: The transfer of a proton, from the acid (proton donor) to the base (proton acceptor). Almost simultaneously and independently, the British chemist Martin Lowry arrived at the same conclusion, thus the name Brønsted–Lowry acid–base theory . Also in 1923, Gilbert N. Lewis proposed an electronic theory of acid–base reactions, but both theories remain commonly used. Later in his career, Brønsted kept studying reaction kinetics, with

1505-402: The wadden sea, vast areas of mud flats , where the guest can experience the exposed seabed. Where national park meets nature park you can also experience the western tip of Denmark, adorned by the lighthouse of Blåvand , with the purpose of guiding ships past Horns Rev , where the sandbank (s) stretch far out into the ocean. If you peer across the ocean from the lighthouse you can often see
