Vedclass · Answer

(C) The thermal stability of alkaline earth metal carbonates increases as the size of the metal cation increases down the group. This is because the larger cation stabilizes the large carbonate anion more effectively. Therefore,the order of increasing thermal stability is $MgCO_3 Conversely,the order of decreasing thermal stability is $BaCO_3 > SrCO_3 > CaCO_3 > MgCO_3$.

The thermal stability of alkaline earth metal carbonates $MgCO_3$,$CaCO_3$,$BaCO_3$,and $SrCO_3$ decreases as:
