A solution contains the metals to Ag+ and Cu+ , each one at a concentration of 0.15 M. If chloride ions are added to the solution the AgCl precipitates first. What is the concentration of the Ag+ remaining in solution when CuCl begins to precipitate? For AgCl, Ksp = 1.82 x 10-13, and for CuCl, Ksp = 1.74 x 10-10
