The solubilites of Na2SO4, BeSO4, MgSO4 and BaSO4 will follow the order (AMU 2010)
A.BeSO4 > MgSO4 > Na2SO4 > BaSO4
B.BeSO4 > Na2SO4 > MgSO4 > BaSO4
C.MgSO4 > BeSO4 > Na2SO4 > BaSO4
D.Na2SO4 > BeSO4 > MgSO4 > BaSO4✓ Correct
Explanation
Solubility of alkali metal sulphates is more than that of alkaline earth metal sulphates. We know the solubility of alkali metal sulphates decreases down the group as the size of the cation of increases thereby decreasing the hydration energy of the compound. Therefore, the order is as follows.
