B

MggtBegtBagtCagtSr

C

BegtMggtCagtSrgtBa

D

MggtCagtBagtBegtSr

Text Solution

Verified by Experts

The correct Answer is:
C
This is mainly due to the reason that as the size of the cation increases, the heat of hydration decreases while the lattice energy remains about the same (because the sulphate anion is no big that increase in size of the cations down the group does not make any difference)solubility decreases in the following order.
`BeSO_4gtMgSO_4gtCaSO_4gtSrSO_4gtBaSO_4`.
