Which of the following carbonates does not evolve `CO_(2)` on heating ?

A

`Li_(2)CO_(3)`

B

`Na_(2)CO_(3)`

C

`K_(2)CO_(3)`

D

`Cs_(2)CO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Li_(2)CO_(3)` being least stable due to size incompatibily of `Li^(o+)` and `CO_(3)^(2Θ)` ions, it decomposes most readily. `Li_(2)CO_(3)overset(Delta)rarr Li_(2)O+CO_(2)`
