WebApr 7, 2024 · Definition of acids according to Arrhenius: Svante Arrhenius, a Swedish chemist, first presented the Arrhenius hypothesis of acids and bases in 1884. He proposed categorising certain substances as acids or bases depending on the type of ions generated when they were combined with water. Hydrochloric acid in the water, for example. WebAn Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H +, or hydrogen, ion.. An Arrhenius base is any substance that gives the OH-, or …
