WebFeb 2, 2024 · The net reaction of CaF 2 with strong acid is thus. CaF2 ( s) + 2H + (aq) → Ca2 + (aq) + 2HF(aq) Example 18.7.1 shows how to calculate the solubility effect of adding a strong acid to a solution of a sparingly soluble salt. Sparingly soluble salts derived from weak acids tend to be more soluble in an acidic solution.
