Question

Demonstrate the process of preparation of carbon dioxide in laboratory.​

Answer 1

Explanation:

Carbon Dioxide Gas Preparation

• Add 5 M hydrochloric acid to 5 - 10 g marble chips. Carbon dioxide gas is released by the chemical reaction.

• Collect the carbon dioxide from the upward displacement of air in a hood. Carbon dioxide is about 60% more dense than air, so it will fill the reaction container.

Reaction:- 2Hcl + CaCO3 ----> 2CaCl + H2O

Answer 2

Answer:

Carbon dioxide is produced whenever an acid reacts with a carbonate. This makes carbon dioxide easy to make in the laboratory. Calcium carbonate and hydrochloric acid are usually used because they are cheap and easy to obtain. Carbon dioxide can be collected over water
