Arrhenius Definition of Acids and Bases - GitHub Pages
Chemists prefer, however, to have definitions for acids and bases in chemical terms. The Swedish chemist Svante Arrhenius developed the first chemical definitions of acids and bases in the late 1800s. Arrhenius defined an acid A compound that increases the concentration of hydrogen ion (H +) in aqueous solution. as a compound that increases the concentration of hydrogen ion (H +) in aqueous
