Arrhenius theory of dissociation
     n : (chemistry) theory that describes aqueous solutions in terms
         of acids (which dissociate to give hydrogen ions) and
         bases (which dissociate to give hydroxyl ions); the
         product of an acid and a base is a salt and water [syn: {theory
         of dissociation}, {theory of electrolytic dissociation}]
