Name the gas evolved when dilute $HCl$ reacts with sodium hydrogen carbonate. How is it recognized?
(N/A) When dilute $HCl$ reacts with sodium hydrogen carbonate $(NaHCO_3)$,the gas evolved is carbon dioxide $(CO_2)$.
The chemical reaction is: $NaHCO_3 + HCl \rightarrow NaCl + H_2O + CO_2 \uparrow$.
This gas is recognized by passing it through lime water $(Ca(OH)_2)$. It turns the lime water milky due to the formation of insoluble calcium carbonate $(CaCO_3)$.
