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

A

`CaSO_(4)`

B

`BeSO_(4)`

C

`BaSO_(4)`

D

`SrSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Be^(2+)` is very small, hence its hydration enthalpy is greater than its lattice enthalpy
`("At. Nos. Mn "=25, Fe=26, Co=27, Ni=28)`
