A solution contains 0.10 M Cu2+ and 0.10 M Mn2+. Can 99.9%
of either ion be precipitated by the addition of OH- without
precipitating the other ion? What will the concentration of
the less soluble ion be when the second hydroxide begins to
precipitate?
Cu(OH)2 Ksp = 4.8 x 10-20 Mn(OH)2 Ksp = 1.6 x 10-13
