A solution is \)0.010 \mathrm{M}\) in \(\mathrm{Ba}^{2+}\) and \(0.020 \mathrm{M} \mathrm{in} \mathrm{Ca}^{2+}\).
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? What minimum concentration of \(\mathrm{Na}_2 \mathrm{SO}_4\) will trigger the precipitation of the cation that precipitates first?
b. What is the remaining concentration of the cation that precipitates first, when the other cation begins to precipitate?
