Question

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.
