Solution

The compound X is ethanoic acid, commonly known as acetic acid. On reaction with sodium bicarbonate, it forms sodium acetate, water and carbon dioxide gas. Thus the brisk effervescence observed is due to carbon dioxide gas. Following is the chemical equation for the reaction
CH₃COOH + NaHCO₃ â†’ CH₃COONa + H₂O + CO₂
