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, as shown in the diagram.

Answer 2

Answer:

Carbon dioxide does not come from an acid but from the action of an acid on a carbonate or a bicarbonate

NaHCO3 + HCl —-> NaCl +H2O+CO2

The CO2 leaves the reaction as a gas and therefore the equilibrium is driven to the right.

One might generate CO2 by heating organic acids to a high temperature in air. More or less burning them
