…In the 20th century, more unified concepts emerged and were established, partly due to the progress of research on reactions in non-aqueous solvents, especially non-aqueous solvents. Among these, the concepts independently announced in 1923 by JN Brønsted (1879-1947) of Denmark and TM Lowry (1874-1936) of England, and the concept by GN Lewis of the United States are particularly important. (1) Brønsted-Lowry concept: An acid is a chemical species that provides protons, and a base is a species that accepts protons. In other words, when considering the equilibrium of acid-HA, HA⇄H + + A- , so HA is considered to be an acid and A- is considered to be a base. … *Some of the terminology references "Brønsted, JN" are listed below.

…20世紀になると,さらに統一的な概念が出現し,またそれぞれに確立したが,これには水溶液以外での反応,とくに非水溶媒系での反応の研究が進んできたことも原因の一つである。このなかでは1923年デンマークのブレーンステズJ.N.Brønsted(1879‐1947)とイギリスのローリーT.M.Lowry(1874‐1936)が独立に発表した概念と,アメリカのG.N.ルイスの概念がとくに重要である。(1)ブレーンステズ=ローリーの概念 〈酸とはプロトンを供給する化学種であり,塩基はプロトンを受容するものである〉,すなわち酸HAの平衡を考えると, HA⇄H++A-であるから,HAは酸であり,A-は塩基であると考えるのである。… ※「Brønsted,J.N.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
