Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 4. Carbon and Its Compounds

Answer :

Salt X is sodium ethanoate, CH₃COONa; Gas Y is carbon dioxide (CO₂)

Activity:

� Take a boiling test tubes and put about 0.5 g of sodium carbonate in it.

� Also, take another tube and add some lime water in it.

� Then add 2 ml of dilute ethanoic acid in the boiling tube A. We will observe that brisk effervescence of carbon dioxide is produce.

� Pass the gas produced through lime water. Lime water turns milky.

� So, this experiment proves that when ethanoic acid reacts with sodium carbonate, then carbon dioxide gas is produced.
