Short Answer
200 mL of an aqueous solution contains 0.030 M concentrations of both Sr2+ and Ca2+. If 100 mL of 2.0 × 10-3 M Na2SO4 is added to this solution will a precipitate form? If so, what will the precipitate be? The Ksp values for SrSO4 and CaSO4 are 2.4 × 10-5 and 3.2 × 10-7.Hint: Remember that the solutions are diluted.
