Which of the following alkaline earth metal sulphates has its hydration enthalpy greater than its lattice enthalpy?

A

`BaSO_4`

B

`SrSO_4`

C

`CaSO_4`

D

`BeSO_4`

Text Solution

Verified by Experts

The correct Answer is:
D
Among alkaline earth metal sulphates, lattice enthalpy remains almost constant but hydration enthalpy decreases down the group. Thus, `BeSO_4` has higher hydration enthalpy as compared to lattice enthalpy.
