Question 47
A salt X is formed and gas is evolved when ethanoic acid reacts with sodium hydrogen carbonate. 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 one which you have named. Also, write chemical equation of the reaction involved.

Solution

X is sodium ethanoate. The gas evolved is carbon dioxide. To check this we can pass the gas through lime water and it will turn lime water milky. The schematic diagram is given below:

The reaction involved is:

CH3COOH+NaHCO3CH3COONa+H2O+CO2
