Solution

(i) Sodium ethanoate is heated with soda lime.

Soda lime is manufactured by adding sodium hydroxide solution to solid calcium oxide (quicklime). It is essentially a mixture of sodium hydroxide, calcium oxide and calcium hydroxide. It comes as white granules.

When sodium ethanoate is heated with soda lime, methane gas is produced.

$C H_{3} C O O N a$ + NaOH $\to$ $C H_{4}$ + $N a_{2} C O_{3}$

(ii) When ethanoic acid $C H_{3} C O O H$ is warmed with methanol $C H_{3} O H$ in presence of concentrated sulphuric acid, pleasant ester methyl ethanoate $C H_{3} C O O C H_{3}$ is formed. This reaction is known as esterification.

$C H_{3} C O O H$ + $C H_{3} O H$ $c o n c . H_{2} S O_{4} - ------ \to$ $C H_{3} C O O C H_{3}$ + $H_{2} O$
