A salt X is formed and a 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 the one which you have named. Also, write chemical equation of the reaction involved.
you have named. Also, write chemical equation of the reaction involved. Ans. Salt X is sodium ethanoate and the evolved gas is carbon dioxide. Take a test tube and take ethanoic acid in it. Add sodium bicarbonate to the acid. Close the mouth of the test tube with a cork and attach a delivery tube to it. Take lime water in another test tube and attach this with another and of delivery tube.
You will observe that the lime water turns milky. This shows that the evolved gas is carbon dioxide. Following reaction takes place between ethanoic acid and sodium hydrogen carbonate.
CH3 COOH + NaHCO3 → CH3 COONa + CO2 + H2 O
