Question

For which salt is the aqueous solubility most likely to change by changing the pH of the solution?

Answer 1

The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).

The pH of a salt solution depends on the nature of the acid and base that forms the salt.

• Salt of a weak acid and a strong base yields a basic solution
• Salt of a strong acid and a weak base yields an acidic solution
• Salt of a strong acid and a strong base yields a neutral solution.

Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.
