An Arrhenius '''acid''', when dissociated in water, typically yields positively-[[electric charge|charged]] [[hydrogen]] ion and a complementary negative [[ion]].

An Arrhenius '''base''', when dissociated in water, typically yields negatively-[[electric charge|charged]] [[hydroxide]] ion and a complementary positive [[ion]].
