$NaHCO_3$

Vedclass · Answer

(B) The correct option is $B$.$NaHCO_3$ (sodium bicarbonate) produces $CO_2$ gas upon heating according to the reaction:$2NaHCO_3 \xrightarrow{\Delta} Na_2CO_3 + H_2O + CO_2$From the stoichiometry,$2 \ moles$ of $NaHCO_3$ produce $1 \ mole$ of $CO_2$. However,the question asks for the salt that produces $CO_2$ and has a carbon content of approximately $14.3 \%$.Molecular mass of $NaHCO_3 = 23 + 1 + 12 + (16 	imes 3) = 84 \ g/mol$.Percentage of carbon in $NaHCO_3 = \frac{12}{84} 	imes 100 \approx 14.28 \%$,which is close to $14.3 \%$.Other salts like $CH_3COONa$ or $HCOONa$ do not produce $CO_2$ upon simple heating in the same manner.

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