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.

Ill give you more points if your answer is right but In fear of getting another disturbing image the points are kinda low for right now

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
