(a) What is vinegar? (b) Describe with a chemical equation, what happens when sodium hydrogen carbonate reacts with ethanoic acid.
(a) Vinegar is 5-8% solution of ethanoic acid (acetic acid) in water. (b) When sodium hydrogen carbonate reacts with ethanoic acid, sodium acetate, carbon dioxide and water are obtained as products. The chemical equation for this process is: CH3COOH + NaHCO3 -CH3COONa + C02+H20
