A: What is the molar solubility of BaSO4 in pure water at 25C?
B: What is the molar solubility of BaF2 in pure water at 25C?
C: A 1.0L solution contains 2.7 • 10^-5 mole SO4-2 and 5.5 • 10^-1 mol F- at 25C. A Ba(NO3)2(aq) solution is added steadily to the first solution. Assume the added Ba(NO3)2 solution does not affect the total volume of the solution
I: Which salt precipitates first?
II: What is the [Ba+2] in the solution when the first precipitate begins to form?
D: As more Ba(NO3)2 is added to the mixture in part (C) a second precipitate begins to form. At that stage, what percent of the anion of the first precipitate remains in the solution?
