Question:
The correct sequence of thermal stability of the following carbonates is
Correct Option: , 2
Solution:
Thermal stability of Alkaline earth metals carbonates increases down the group.
because down the group polarizing power of cation decreases. So thermal stability increases.
Hence, Thermal stability order :
$\mathrm{MgCO}_{3}<\mathrm{CaCO}_{3}<\mathrm{SrCO}_{3}<\mathrm{BaCO}_{3}$
