Acids on the other hand would contribute #H^+# ions when dissociated. The easiest way to identify Arrhenius bases is to identify #OH^-# in a compound formula.
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).
