Molar solubility of copper hydroxide in pure water, taken intoaccount that water is adding hydroxide into the solution.Ksp=[Cu^2+][OH^-]^2 = 4.8x10^-20

(x) (1.0x10^-7 +2x)^2 = 4.8x10^-20

Cu(OH)2 ---------> Cu+2 (aq) + 2OH- (aq)

                       I         0            1*10-7

                             C        x              2x

                     E         x           1*10-7 +2x

                     ksp = [Cu+2][OH]2

    4.8*10-20         = x*(1*10-7 +2x)2

            x   = 1.96*10-7 M

molar solubility of Cu(OH)2 = 1.96*10-7 M
