In qualitative analysis, the metals of Group I can be separated from other ions by precipitating them as chloride salts. A solution initially contains Ag+ and Pb2+ at a concentration of 0.10 M. Aqueous HCl is added to this solution until the Cl– concentration is 0.10 M. What will the concentration of Ag+ and Pb2+ at equilibrium?
(Ksp for AgCl = 1.8 × 10-10)
(Ksp for PbCl2 = 1.7 × 10-5)
