How is carbon dioxide prepared and collected in a 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 can be collected over water, as shown in the diagram. read more

To prepare carbon dioxide in the laboratory. Aids: Woulf’s bottle; Gas jar with lid; Marble chips; Dilute hydrochloric acid; Method: 1. Put some marble chips in a Woulf’s bottle and fit the bottle with a thistle funnel and a delivery tube. 2. Place a collecting jar at the other end of the delivery tube. 3. read more

In the laboratory the gas is made by pouring dilute hydrochloric acid on to marble chips (CaCO3). read more

Carbon dioxide can be collected over water, as shown in the diagram. Carbon dioxide is slightly soluble. in water and denser. than air, so another way to collect it is in a dry, upright gas jar. As the carbon dioxide falls out of the delivery tube and into the gas jar, it pushes the less dense air out of the top of the gas jar. read more
