A solution contains 0.010 M F− and 0.010 M CO32−. If Mg2+ is slowly added to the solution, which ion will precipitate first? What is the maximum concentration of Mg2+ that can be used to selectively precipitate out one metal ion, leaving the other ion in solution? The Ksp of MgF2 is 5.0x10−9 and the Ksp of MgCO3 is 5.0x10−8.
