Thermal stability of II A carbonates from `BeCO_(3)` to `BaCO_(3)`

A

Increases

B

Decreases

C

May increases (or) decreases

D

Can not be in a regular

Text Solution

Verified by Experts

The correct Answer is:
A
As lattice energy of corresponding oxides decreases from Be to Ba the4 thermal stability of their carbonates increases from `BeCO_(3)` to `BaCO_(3)`.
