A solution contains 0.01 M Zn2+ and Cu2+ ions. It is saturated by passing H2S gas in the solution. The solubility products of ZnS and CuS are 3.0 × 10-22 and 8.0 × 10-36 respectively. Which of the following is true? K1 = 10-7 , K2 = 10-14 , [H2S, aq]saturated = 0.1 M
(A) ZnS will precipitate
(B) CuS will precipitate
(C) Both ZnS and CuS will precipitate
(D) Both Zn2+ and Cu2+ will remain in the solution
