A mining operation needs to separate silver and copper. You are hired as a summer intern in a beautiful Colorado mining town, and one of your tasks is to determine whether this separation can be accomplished by oxidizing the metals to Ag+ and Cu+, each one at a concentration of 0.15 M, and then precipitate one as the chloride salt without precipitate the other. AgCl precipitates first. What is the concentration of the Ag+ remaining in solution when CuCl begins to precipitate? For AgCl, pKsp = 9.74. and for CuCl, pKsp = 6.76.
