A solution is 0.0100 M in each of the metal ions in the following table:
| Metal sulfide | Kspa |
| FeS | 6×102 |
| NiS | 8×10-1 |
| PbS | 3×10-7 |
| CuS | 6×10-16 |
HCl is added to the solution so that the H3O+ concentration is 0.300 M. H2S gas is bubbled through the solution to attain a H2S concentration of 0.100 M. Predict which of the sulfides precipitate under the given conditions

Hydrogen sulfide (H2S) is a diprotic weak acid which can be used to selectively precipitate metal sulfide compounds from solution. The two deprotonation reactions of hydrogen sulfide are provided below along with their respective acid dissociation constants. H2S(ag) + H2O7) = HS (an) + H30+(aq) Kal = 1.0 * 10-7 HS (aq) + H2O) = 52 (ag) + H30 (29) K22=1 * 10-19 Imagine you have an aqueous solution buffered at pH 3...
