The solubility of `Na_(2),SO_(4),BeSO_(4),MgSO_(4) and BaSO_(4)` will follow the order

A

`BeSO_(4)gtMgSO_(4)gtNa_(2)SO_(4)gtBaSO_(4)`

B

`BeSO_(4)gNaSO_(4)gtMgSO_(4)gtBaSO_(4)`

C

`MgSO_(4)gtBeSO_(4)gtNa_(2)SO_(4)gtBaSO_(4)`

D

`Na_(2)SO_(4)gtBeSO_(4)gtMgSO_(4)gtBaSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Na_(2)SO_(4)` is most soluble because alkali metal sulphates are more as compared to alkaline earth metal sulphates. Among alkaline earth metal sulphates `BeSO_(4)` is most soluble. This is because on moving downward, the magnitude of lattice energy remains almost cosntant (due to large sized sulphate ion) but hydration energy decreases. Hence, the order of solubility is
`Na_(2)SO_(4)gtBeSO_(4)gtMgSO_(4)gtBaSO_(4)`
