2. A solution is 0.01 M in Ba2+ and 0.01 M in Ca2+. Sodium sulfate is added to selectively precipitate one of the cations, while leaving the other in solution. a) Given that BaSO4 and CaSO4 have Ksp values of 1.07 x 10-10 and 7.10 x 10-5 respectively, which cation will precipitate first? Explain why. b) What is the minimum concentration of SO42⁻ that will trigger the precipitation of the cation that precipitates first?
