How is carbon dioxide gas prepared in laboratory?

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 Reactants

Only two materials are needed to make carbon dioxide:

calcium carbonate (marble chips)

5 M hydrochloric acid

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.

Chemical Reaction

2HCl + CaCO3 → CO2+ CaCl2 + H2O
