Given the chоice оf аdding iоns of Mg 2+ (аq), Cа 2+ (aq), Sr 2+ (aq) or Ba 2+ (aq) to a solution of carbonate ions, CO3 2-, which choice would precipitate an insoluble carbonate compound first? Use the following Ksp data: MgCO3 Ksp = 6.82 × 10-6 CaCO3 Ksp = 4.96 × 10-9 SrCO3 Ksp = 9.30× 10-10 BaCO3 Ksp = 5.00 × 10-9
