प्रश्न
A gas is liberated immediately with a brisk effervescence, when you add acetic acid to sodium hydrogen carbonate powder in a test tube. Name the gas and describe the test that confirms the identity of the gas.

उत्तर
When acetic acid (CH3COOH) is added to the sodium hydrogen carbonate (NaHCO3) powder in a test tube, then the products obtained are sodium acetate, carbon dioxide and water.
Observations in this reaction are:
Brisk effervescence is seen because of CO2 gas escaping out from the reaction mixture. The gas turns lime water milky that confirms the identity of CO2 gas.
Chemical reactions involved:
CH3COOH + NaHCO3 →CH3COONa + CO2↑ + H2O
Ca(OH)2 + CO2 → CaCO3↓ + H2O
