MY and NY3, two nearly insoluble salts, have the same Ksp values of 6.2×10-13 at room temperature. Which statement would be true in regard to MY and NY3 ?

For MY:Ksp=s12⇒s1=Ksp=6.2×10-13=7.87×10-7 mol L-1For NY3:Ksp=27s24⇒s2=6.2×10-13274⇒s2=3.89×10-4 mol L-1Hence, molar solubility of MY  in water is less than that of NY3 .
