Vedclass · Answer

(A) The thermal stability of metal carbonates increases as we move down the group in the periodic table due to the increase in the electropositive character of the metal.For Group $2$ elements,the thermal stability order is $BeCO_3 Group $1$ carbonates (like $K_2CO_3$) are generally more thermally stable than Group $2$ carbonates because Group $1$ metals are more electropositive and form more basic oxides.Therefore,the overall order of thermal stability is $BeCO_3 < MgCO_3 < CaCO_3 < K_2CO_3$.

Arrange the following in the correct order of thermal stability:
$K_2CO_3, MgCO_3, CaCO_3, BeCO_3$
