If a solution contains 0.10 M Na+, 0.10 M Ba2+, 0.10 M Pb+2, and 0.10 M Ag+ determine the following:

a. Using Ksp, which of ions would precipitate first when adding 0.10 M of potassium sulfate?

b. What % of either ion can be precipitated out by the addition of potassium sulfate, without co-precipitation occurring? (Hint: you can try random percentages until you find your limit.

c. How much of the Na ion could be precipitated if I changed the precipitating agent to KCl?
