Consider a solution of 0.1 M Zn^2+ and 0.1 M Cu^2+ that is saturated with H2S. You will encounter a simiar mixture in this experiment. The solubility product constants for ZnS and CuS are 1.1x10^-21 and 6x10^-36, respectively. A.) Show that both ZnS and CuS will precipitate at pH8. B.) Show that only CuS will precipitate when [H3O+]=0.3 M.
