A compound of sodium does not give CO(2)...

A compound of sodium does not give `CO_(2)` when heated but it gives `CO_(2)` when treated with dilute acids. A crystalline compound is found to have 37.1 percent Na and 1.6 percent `Ho_(2)`. Hence the compound is

A

`NaHCO_(3), 10H_(2)O`

B

`NaHCO_(3).5H_(2)O`

C

`Na_(2)CO_(3).10H_(2)O`

D

`Na_(2)CO_(3). H_(2)O`

Verified by Experts

The correct Answer is:

D

`Na_(2)CO_(3)xxH_(2)O`
`4600=3932.6 +667.8x`
`667.4=667.8x,x=1`
