    The ion product constant expression for water is Kw = [H^+][OH^-] = 1.0 x 10^-14

    Your question stops in the middle somewhere but I assume you want the other unknown.

    [H^+] = Kw/[OH^-] = (1.0 x 10^-14)/(1.2 x 10^-2) = 8.3 x 10^-13 M

    Hope this is helpful to you. JIL HIR

    The multiplication of the ionization of H+ and OH- in water is mostly a million x 10E-14. So take the numbers in yur subject and divide them right into a million x 10 E-14 and additionally you have your answer. to illustrate, your first answer would be a million x 10 E-10
