Problem- Consider a solution that is 0.010 M in Ba2+ and 0.020 M in Ca2+.
a. If sodium sulfate is used to selectively precipitate one of the cations while leaving the other cation in solution, which cation will precipitate first (look up the Ksp values in your text)? What minimum concentration of Na2SO4 is required to cause the precipitation of the cation that precipitates first?
b. What minimum concentration of Na2SO4 is required to cause the precipitation of the cation that precipitates second? I have no idea how to do this...Do you make 2 equations?
