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.
Calcium hydroxide is an Arrhenius base. You can see that it consists of a cation (we know calcium should be a cation because it is a metal on the left side of the periodic table bonded to elements on the right side). The anions are hydroxyl groups. #Ca(OH)_2->Ca^(2+)+2OH^-#.
