Write the chemical equations for the reactions of ethanoic acid with the following:
$(a)$ Sodium
$(b)$ Sodium hydroxide
$(c)$ Ethanol
Also,write the name of one main product for each reaction.

The oxidising agent which can oxidise ethanol to ethanoic acid is:

Which of the following is the reaction occurring between alcohol and carboxylic acid in the presence of concentrated $H_{2}SO_{4}$?

$A$ salt $X$ is formed and a gas is evolved when ethanoic acid reacts with sodium hydrogencarbonate. Name the salt $X$ and the gas evolved. Describe an activity and draw the diagram of the apparatus to prove that the evolved gas is the one which you have named. Also,write the chemical equation of the reaction involved.

What happens when a small piece of sodium is dropped into ethanol?
