Which one of the alkaline earth metal carbonates is thermally the most stable?

A

`MgCO_(3)`

B

`CaCO_(3)`

C

`SrCO_(3)`

D

`BaCO_(3)`

Text Solution

Verified by Experts

As the electropositive character of the metal increases or the basicity of their hydroxides increases down the group, their thermal stability increases . Thus , `BaCO_(3)` is the most stable and hence option (d) is correct .
