Problem

Separate saturated solutions of CaF₂(s) and MgF₂(s) are each brought to 0.050 M NaF (no volume change). Given

K_{sp}(\text{CaF}_2)=1.5\times10^{-10}

and

K_{sp}(\text{MgF}_2)=6.3\times10^{-9}

, determine which salt experiences the greater percentage decrease in its molar solubility. Show any needed calculation briefly.
