(a) When ethanoic acid reacts with sodium hydrogencarbonate then a salt X is formed and a gas Y is evolved. Name the salt X and gas Y. Describe an activity with the help of a labelled diagram of the apparatus used to prove that the evolved gas is the one which you have named . Also write the chemical equation of the reaction involved
(b) Give any two uses of ethanoic acid.

Explanation

Salt X is sodium ethanoate, `CH_(3)COONa`;
Gas Y is carbon dioxide", `CO_(2)`;
Gas Y turns lime water milky is sodium ethanoate, `CH_(3)COONa`;
Gas Y is carbon dioxide, `CO_(2)`;
Gas Y turns lime water milky.
