Question

What happens when: (Write chemical reactions as well)
 (i) Sodium ethanoate is heated with soda lime.
 (ii) Ethanoic acid is warmed with methanol in the presence of concentrated sulphuric acid.


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.

  CH3COONa + NaOH CH4 + Na2CO3

 (ii) When ethanoic acid CH3COOH is warmed with methanolCH3OH  in the presence of concentrated sulphuric acid, pleasant ester methyl ethanoate CH3COOCH3 is formed. This reaction is known as esterification.

 CH3COOH  +  CH3OH conc.H2SO4−−−−−−  CH3COOCH3   +  H2O
