One mole of one of sodium salt listed be...

One mole of one of sodium salt listed below, having carbon content close to 14.3% produces 1 mole of carbon dioxide upon heating ( atomic mass Na=23, C=12,O=16 ). The salt is

A

`C_(2)H_(5)COONa`

B

`NaHCO_(3)`

C

`HCOONa`

D

`CH_(3)COONa`

Text Solution

Verified by Experts

The correct Answer is:
B
`2NaHCO_(3) overset(Delta) to Na_(2)CO_(3) + H_(2)O + CO_(2)`
% of `C = (12)/(84) xx 100 =14.28`%
This question can be done by checking % of carbon 14.2% comes only in `NaHCO_(3)`
