Statement I : Sparingly soluble salts AB and XY2 with the same solubility product, will have different solubility.Statement II : solubility of sparingly soluble salt depend upon solubility product.

AB(s)⇌AB(aqS1)→A+S1(aq)+B-S1(aq)(Ksp)AB = S1 x S1 = S12XY2(s)⇌XY2(aq)→XS2+2(aq)+2Y2S2-(aq)KspXY2=S2×2S22=4S23Even if Ksp for both the salts are same, they will have different values of solubilities.Solubility product depends on solubility and stoichiometry.( also on temperature)
