$Li_2CO_3$

Vedclass · Answer

(A) Among the alkali metal carbonates,$Li_2CO_3$ is thermally unstable because of the small size of the $Li^+$ ion,which has a high polarizing power. It decomposes upon heating as follows: $Li_2CO_3 \xrightarrow{\Delta} Li_2O + CO_2$. Other alkali metal carbonates like $Na_2CO_3$ are thermally stable due to the larger size of the alkali metal cations.
