(B) For pure water,the concentration of hydronium ions is equal to the concentration of hydroxide ions: $[H_3O^{+}] = [OH^{-}]$.Given $[H_3O^{+}] = 10^{-6}\,M$,therefore $[OH^{-}] = 10^{-6}\,M$.The ionic product of water is defined as $K_w = [H_3O^{+}][OH^{-}]$.Substituting the values: $K_w = (10^{-6}) \times (10^{-6}) = 10^{-12}$.
