WebSep 15, 2024 · The Swedish chemist Svante Arrhenius developed the first chemical definitions of acids and bases in the late 1800s. Arrhenius defined an acid as a compound that increases the concentration of hydrogen ion (H +) in aqueous solution. Many acids are simple compounds that release a hydrogen cation into solution when they dissolve. WebJames C. Blackstock, in Guide to Biochemistry, 1989 2.4 pH scale.
