- There is a solution containing two metal cations. The goal is to separate them by slowly and carefully adding a solution of an anion, until one mental cation precipitates as a compound with that anion, leaving the other metal cation still in solution. M+ is Ag+, M2+ is Ca2+, anion is SO4 2-, first Ksp is 1.2 x 10-5, second Ksp is 6.1 x 10-5, and the starting concentrations of M+ is 1.50 x 10-2 M and M2+ is 3.50 x 10-2M. Using these values, predict which metal will precipitate first and what concentration of anion the precipitation will begin.What is the solubility of La(IO3)3 in a solution that contains 0.100 M IO3- ions?
