The compound 'A' on heating gives a colourless gas and a residue. The residue dissolves in water to obtain (B). When excess of `CO_(2)` is bubbled through aqueous solution of B gentle heating gives back A.
Compound 'C' is

A

`CaCO_(3)`

B

`Ca(HCO_(3))_(2)`

C

`NaCO_(3)`

D

`NaHCO_(3)`

Text Solution

Verified by Experts
