In principle, the ions Ba 2+ and Ca 2+ can be separated by the difference in solubility

Question:

In principle, the ions Ba²⁺ and Ca²⁺ can be separated by the difference in solubility of their fluorides, BaF₂ and CaF₂. If you have a solution that is 0.10 M in both Ba²⁺ and Ca²⁺, CaF₂ will begin to precipitate first as fluoride ion is added slowly to the solution.
(a) What concentration of fluoride ion will precipitate the maximum amount of Ca²⁺ ion without precipitating BaF₂?
(b) What concentration of Ca²⁺ remains in solution when BaF₂ just begins to precipitate?
