On heating which of the following release `CO_(2)` most easily ?

A

`K_2CO_3`

B

`Na_2CO_3`

C

`MgCO_3`

D

`CaCO_3`

Text Solution

Verified by Experts

The correct Answer is:
C
Order of thermal stability is `K_2CO_3 gt Na_2CO_3 gt CaCO_3 gt MgCO_3`
Hence, `MgCO_3` releases `CO_2` most easily
`MgCO_3overset(Delta)to MgO+CO_2`
