The solubility product, Ksp, for cobalt(III) hydroxide, Co(OH)3, is 1.6 ✕ 10−44 at 25°C. What is the molar solubility of cobalt(III) hydroxide in a solution containing 0.062 M KOH at 25°C?

Solutions

Expert Solution

Co(OH)3 ---------------> Co^+3 (aq) + 3OH^-

                                        s                    3s

                                                               

                                                               3s+0.062

            Ksp   = [Co^+3][OH^-]^3

                    = s*(3s+0.062)^3              [ 3s+0.062 = 0.062]

        1.6*10^-44 = s*(0.062)^3

        s                = 1.6*10^-44/(0.062)^3 = 6.7*10^-41 M

solubility   = 6.7*10^-41 M >>>>>answer
