1. Arrhenius definition. : An acid is a substance that dissociates in water to produce H+ ions (protons), and a base is a substance that dissociates in water to produce OHâions (hydroxide); an acid-base reaction involves the reaction of a proton with the hydroxide ion to form water. 2.
This refers to the BrÃ¸nsted-Lowry theory of acids and bases. Alternative definitions of bases include electron pair donors (Lewis), and as sources of hydroxide anions (Arrhenius). Examples of simple bases are sodium hydroxide (NaOH, which is thus an alkali and base) and ammonia (NH3 which is not 'alkali' but base).
