उत्तर
When sodium hydrogen carbonate is added to a flask containing acetic acid, the two observations noted are as follows:
(i) Brisk effervescence is seen because of CO2 gas escaping out from the reaction mixture. The gas turns lime water milky.
(ii) Some amount of heat is evolved during the reaction.
Reactions:\[{NaHCO}_3 + {CH}_3 COOH \to {CH}_3 COONa + {CO}_2 \uparrow + H_2 O\]
\[Ca \left( OH \right)_2 + {CO}_2 \to {CaCO}_3 + H_2 O\]
