An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion.

An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water.

Arrhenius acids include compounds such as HCl, HCN, and H2SO4 that ionize in water to give the H+ ion. Arrhenius bases include ionic compounds that contain the OH- ion, such as NaOH, KOH, and Ca(OH)2.

This theory explains why acids have similar properties: The characteristic properties of acids result from the presence of the H+ ion generated when an acid dissolves in water. It also explains why acids neutralize bases and vice versa. Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water.

H+(aq) + OH-(aq) -----> H2O(l)
