(N/A) $(a) (i)$ $2CH_{3}COOH + 2Na ightarrow 2CH_{3}COONa + H_{2} \uparrow$$(ii)$ $2CH_{3}COOH + Na_{2}CO_{3} ightarrow 2CH_{3}COONa + H_{2}O + CO_{2} \uparrow$$(iii)$ $CH_{3}COOH + C_{2}H_{5}OH \xrightarrow{	ext{conc. } H_{2}SO_{4}} CH_{3}COOC_{2}H_{5} + H_{2}O$$(b)$ Concentrated sulphuric acid acts as a dehydrating agent. It removes the water molecule formed during the reaction,which shifts the equilibrium forward,thereby increasing the yield of the ester.$(c)$ Ethanoic acid is used as a preservative in pickles and for making vinegar.

$(a)$ Write chemical equations for the reactions of ethanoic acid with:
$(i)$ Sodium
$(ii)$ Sodium carbonate
$(iii)$ Ethanol in the presence of conc. $H_{2}SO_{4}$.
$(b)$ State the role of concentrated sulphuric acid in the esterification reaction.
$(c)$ Write one use of ethanoic acid.
