The cations in an aqueous solution that contains 0.150 M Ba(NO3)2 and 0.0800 M Ca(NO3)2 are to be separated by taking advantage of the difference in the solubilities of their sulfates. Ksp(BaSO4) = 1.1 × 10-10 and Ksp(CaSO4) = 2.4 × 10-5 . What should be the concentration of sulfate ion for the best separation?
