Vedclass · Accepted Answer

$Li_2CO_3$

Vedclass · Answer

(A) Among alkali metal carbonates,only $Li_2CO_3$ decomposes on heating because of the small size of the $Li^+$ ion,which polarizes the carbonate ion effectively.The reaction is: $Li_2CO_3 \xrightarrow{\Delta} Li_2O + CO_2 \uparrow$Other alkali metal carbonates like $Na_2CO_3$ are thermally stable and do not decompose under ordinary heating conditions.
