Answer

Add Sodium Carbonate (Na2CO3) / Sodium Hydrogen Carbonate (NaHCO3) solution to Ethanol and ethanoic acid. With Ethanol it will produce brisk effervescence of carbon dioxide (CO2) gas whereas no effervescence is seen with Ethanol.

The chemical equation for reaction between Sodium Carbonate (Na2CO3) / Sodium Hydrogen Carbonate (NaHCO3) and Ethanoic Acid is given below:

2CH3COOH + Na2CO3 ⟶ 2CH3COONa + H2O + CO2

CH3COOH + NaHCO3 ⟶ CH3COONa + H2O + CO2
