Ethanoic acid reacts with sodium carbonate to give
- A. sodium ethanoate, water and carbon dioxide
- B. sodium ethanoate and hydrogen
- C. ethanol and carbon dioxide
- D. no reaction
Explanation
Being a stronger acid than carbonic acid, ethanoic acid displaces carbon dioxide from a carbonate, and the effervescence produced is the standard test that distinguishes a carboxylic acid from both alcohols and phenols. With sodium metal the acid would give hydrogen instead. Neutralisation with an alkali gives only the salt and water.
