Vedclass · Answer

(D) The thermal stability of metal carbonates generally increases as the electropositive character of the metal increases. Alkali metal carbonates (Group $1$) are thermally very stable compared to transition metal or alkaline earth metal carbonates. Among alkali metal carbonates,stability increases down the group as the size of the cation increases,which reduces the polarizing power of the cation on the carbonate ion. $K_2CO_3$ is more stable than $Na_2CO_3$ because $K^+$ has a larger ionic radius than $Na^+$. However,$Na_2CO_3$ and $K_2CO_3$ are both highly stable,but $K_2CO_3$ is generally considered more stable due to the larger size of the $K^+$ ion.
