Write chemical equations for what happen when

(i) Sodium metal is added to ethanoic acid


(ii) Solid sodium carbonate is added to ethanoic acid.


(iii) Ethanoic acid reacts with a dilute solution of sodium hydroxide.

(i) When Sodium metal is added to Ethanoic acid, it yields Sodium Ethanoic acid and Hydrogen gas is involved. The chemical equation is as follows:

2Na + 2CH3COOH 2CH3COONa + H2


(ii) When Solid sodium carbonate i.e. Na2CO3 is added to the Ethanoic acid, it gives Sodium Ethanoate CH3COONa along with Carbon dioxide and water.


Na2CO3+ 2CH3COOH 2CH3COONa + CO3+ H2O


(iii) When Ethanoic acid reacts with dilute solution of sodium hydroxide NaOH, the products formed are: Sodium Ethanoate and water


CH3COOH + NaOH (dil.) CH3COONa + H2O
