2 x 10^(-4) mole each of Mn(2+) and Cu(2+) were contained in 1 litre of 0.003 M HClO4 solution and this solution was saturated with H2S. Determine whether or not each of the Mn(2+) and Cu(2+) will precipitate as the sulfide. K(sp - CuS) = 8.5 x 10^(-36); K(sp - MnS) = 2.2 x 10^(-21); K(H2S) = 1 x 10^(-21)
