The decomposition temperature is lowest for

A

`BeCO_(3)`

B

`MgCO_(3)`

C

`SrCO_(3)`

D

`BaCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`BeCO_(3)` is least stable (low decomposition temperature) due to small size of `Be^(+2)` ion which is unstable to stablize biggest `CO_(3)^(2-)` ion.
