This is the reason for its basic nature. When borax is dissolved in water it ionizes and hydrolysis of borate ion gives OH (the hydroxyl ion) and boric acid. Since boric acid is a weak acid AND Na-OH is strong a alkali an aqueous solution of borax is alkaline in nature. ... That's what makes this solution alkaline.
