(B) The ionic product of water is given by the expression: $K_w = [H_3O^{+}][OH^{-}]$.For pure water,the concentration of hydronium ions is equal to the concentration of hydroxide ions: $[H_3O^{+}] = [OH^{-}] = 10^{-6}\, mol\, L^{-1}$.Substituting these values into the expression for $K_w$:$K_w = (10^{-6}) \times (10^{-6}) = 10^{-12}$.
