$MY$ and $NY_3$,two nearly insoluble salts,have the same $K_{sp}$ values of $6.2 \times 10^{-13}$ at room temperature. Which statement would be true in regard to $MY$ and $NY_3$?
- AThe salts $MY$ and $NY_3$ are more soluble in $0.5 \ M \ KY$ than in pure water.
- BThe addition of the salt of $KY$ to solution of $MY$ and $NY_3$ will have no effect on their solubilities.
- CThe molar solubilities of $MY$ and $NY_3$ in water are identical.
- DThe molar solubility of $MY$ in water is less than that of $NY_3$.
