$MY$ and $NY_3$, two nearly insoluble salts, have the same KSP values of $6.2 \times 10^{–13}$ at room temperature. Which statement would be true in regard to $MY$ and $NY_3$ ?

Question

( A ) The molar solubility of $MY$ in water is less than that of $NY_3$
( B ) The salts $MY$ and $NY_3$ are more soluble in 0.5 M $KY$ than in pure water
( C ) The molar solubilities of $MY$ and $NY_3$ in water are identical
( D ) The addition of the salt of $KY$ to solution of $MY$ and $NY_3$ will have no effect on their solubilities
