The two solids CuBr(s) and AgBr(s) are only very slightly soluble in water: Ksp(CuBr) = 4.2 × 10-8and Ksp(AgBr) = 7.7 × 10-13. Some CuBr(s) and AgBr(s) are both mixed into a quantity of water that is then stirred until it is saturated with respect to both solutes. Next, a small amount of KBr is added and dissolves completely. Compute the ratio of [Cu+] to [Ag+] after the system reestablishes equilibrium.
