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.
In 1923, chemists Johannes Nicolaus BrÃ¸nsted and Thomas Martin Lowry independently developed definitions of acids and bases based on the compounds' abilities to either donate or accept protons (\(H^+\) ions). In this theory, acids are defined as proton donors; whereas bases are defined as proton acceptors.
