Question

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.

Answer 1

When ethanoic acid reacts with Sodium Hydrogen Carbonate with production of Sodium Ethanoate and producing Carbon dioxide gas.

CH₃COOH + NaHCO₃ → CH₃COONa + H₂O + CO₂ 

Here salt X is Sodium Ethanoate and gas eveolved is Carbon dioxide.

Activity:

 

• Set up the experiment as shown in figure.
• Take a spoon full of Sodium Hydrogen Carbonate in a test-tube and add 2 ml of dilute ethanoic acid.
• Brisk effervescence occur in test tube.
• Pass the produce gas into lime water.
• Lime water turn milky confirming the evolution of CO₂
