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.
By the 1884 definition of Svante Arrhenius (Sweden), an acid is a material that can release a proton or hydrogen ion (H +). Hydrogen chloride in water solution ionizes and becomes hydrogen ions and chloride ions. If that is the case, a base, or alkali, is a material that can donate a hydroxide ion (OH-).
