Gustav Buchböck

* Bratislava, February 15, 1869 – † Budapest, October 1, 1935 / chemist, university professor, corresponding member of the Hungarian Academy of Sciences (1904) ; ; He completed his university studies in Budapest, receiving his doctorate in 1896. While a university student, he worked as an intern at the Károly Than Institute, then as an assistant professor there, in 1902 as an assistant professor, and in 1904 as a private teacher of general chemistry. During his longer study trip to Germany, he participated in the research work directed by W. Ostwald (1853–1932) and W. Nernst (1864–1941). From 1908, he was deputy of the III. Institute of Chemistry, established by dividing the former Károly Than Department, in 1909 as a public extraordinary professor, and in 1924 as a public full professor. He was one of the first practitioners of the relatively young discipline of physical chemistry in Hungary. He developed a method for examining ion hydration, in which he added known amounts of an indifferent electrolyte to the solution to be examined, and after electrolysis he deduced the difference in hydration of the anion and cation from the change in concentration. From a suitable formula, which also includes the transfer number, ; the number of hydrated water molecules can be calculated. ; He also conducted numerous reaction kinetic studies and established a relationship between reaction rate and internal friction. His book Physikai-chémiai mérőmódszerek, published in 1922, was the first practical handbook on this topic in Hungarian. Among his famous students, we should mention György Hevesy (1885–1966), who was awarded the Nobel Prize in Chemistry in 1943, and Tibor Erdey-Grúz (1902–1976), a physical chemist, university professor, and president of the Hungarian Academy of Sciences. ; ; His main works: ; On the rate of hydrolytic decomposition of carbonyl sulfide, 1896, ; The theory of ions, 1903, ; The influence of the medium on the rate of reaction, 1911, ; The hydration of ions, 1912, ; Experimental chemistry (textbook – written after B. G.'s lectures by Rex S.), 1912, ; General and inorganic chemistry (textbook), 1914, ; Physical-chemical measurement methods, 1921, ; Organic Chemistry (written based on his lectures by Sándor Rex), Bp. 1930.
