In a qualitative analysis procedure, a chemist adds 0.2 M HCl to anunknown group of ions and then saturates the solution withH2S. (H2S = 0.10 M.)
(a) What is the [HS-] of the solution?
(b) If 0.01 M of each of the following ions is in the solution,which will form a precipitate? (Select all that apply.)
Cu2+
Pb2+
Hg2+
