The initial concentrations of Pb2+ and Ag+ are 0.05M and for Cl- 1.5M. Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determine how much Ag+ remains in solution (in M)? Express your answer to two significant figures. The Ksp for AgCl = 1.8 x 10-10 and the Kf for AgCl2- = 1.8 x 105.
