A student adds 0.0035 mol of NaF to 1.00 L of 0.02 M barium nitrate, Ba(NO3)2. Which of the following statements is correct? Ksp = 1.5 × 10–6 for BaF2. Assume there is no volume change upon addition of NaF. One must know Ksp for barium nitrate to make a determination Barium fluoride precipitates until the solution is saturated. The solution is unsaturated and no precipitate forms. The solubility of barium fluoride is increased upon the addition of fluoride ions....

What is the molar solubility of barium fluoride in a solution that contains 2.50 M acetic acid and 3.25 M sodium acetate? Hint: Combine two equilibria reactions to determine the Kc for: BaF2 (s) + 2 H+(aq) + Ba2+(aq) + 2 HF(aq) and then solve for the molar solubility using the approximation method. Be sure to validate! Think about what the total concentration of fluoride ion must be, both as the free F- and as HF.
