Which one 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
In case of `BeSO_(4)` the size of `Be^(2+)` ion is very samll. Therefore, the ion has the maximum tendency to get hydrated. AS a result, the hydration enthalpy of `BeSO_(4)` is more than its lattice enthalpy. For more detail, consult section 10.14
