Consider a solution that contains Ca2+ and Pb2+ ions, both at 0.010 M. If solid Na2SO4 is slowly added to the solution, which precipitates first? What is the concentration of the first
ion that precipitates when the second salt begins to precipitate?
The Ksp for CaSO4 and PbSO4 are 6.1 × 10−5 and 1.3 × 10−8, respectively.
