Vedclass · Answer

(A) The thermal stability of metal carbonates depends on the electropositive nature of the metal. As the electropositive character of the metal increases,the thermal stability of its carbonate increases. For Group $2$ elements,the electropositive character increases down the group $(Be Group $1$ metals are more electropositive than Group $2$ metals,so $K_2CO_3$ is more stable than the alkaline earth metal carbonates. Therefore,the correct order is $BeCO_3 < MgCO_3 < CaCO_3 < K_2CO_3$.

The correct order of increasing thermal stability of $K_2CO_3$,$MgCO_3$,$CaCO_3$ and $BeCO_3$ is
