One way to remove lead ion from water is to add a source of iodide ion so that lead iodide will precipitate out of solution:

Pb2+ (aq) + 2I- (aq) ? PbI2(s)

a. What volume of a 1.0 M KI solution must be added to 100.0 mL of a solution that is 0.15 M in Pb2+ ion to precipitate all the lead ion?

b. What mass of PbI2 should precipitate?
