A

`BeSO_(4)`

B

`CaSO_(4)`

C

`MgSO_(4)`

D

`SrSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Sulphates of alkaline earth metals are all white slids and ralatively more stable to heat that the correesponding carbonates. On heating they all decompose giving the metal oxides:
`MSO_(4)overset(Delta)toMO+SO_(3)`
The more basic the metal, the more stable is the sulphate thus, like carbonates, the temperature of decomposition (related to thermal stability) of sulphates of group 2 elements increases as the electropositive character of the metal or the basic strength of metal hydroxide increases down the group.
