Question: A solution has 2.0 x 10-2 Pb2+ and 1.0 x 10-2 M Ag+ in it. Both AgCl (Ksp=1.8x10-10) and PbCl2 (Ksp=1.7x10-5) precipitate from the solution

A solution has 2.0 x 10-2 Pb2+ and 1.0 x 10-2 M Ag+ in it. Both AgCl (Ksp=1.8x10-10) and PbCl2 (Ksp=1.7x10-5) precipitate from the solution when Cl- is added. What concentration of Cl- is required to start each salt's precipitation? What salt precipitates first?
