Which of the following will show a pH dependence (acid dependence) on solubility? I. CaF2 II. PbI2. III. Ni(CN)2
The correct answer is I. CaF2 .
Explanation : CaF2 is a salt of strong base CaCO3 and weak acid HF. If the concentration of H+ or OH- changes in the solution the concentration changes which leads to change in solubility.
