An organic compound X of molecular formula C2H4O2 turns blue litmus to red and gives brisk effervescence with Na2CO3 and NaHCO3. Identify X and name of the gas responsible for effervescence.
X is ethanoic acid (CH3COOH). It is acidic and hence turns blue litmus red. It releases carbon dioxide (CO2) when treated with Na2CO3 and NaHCO3 which is responsible for effervescence.
2CH3COOH + Na2CO3→ 2CH3COONa + CO2↑ + H2O
CH3COOH + NaHCO3→ CH3COONa + CO2↑ + H2O
