It is inserted in the apparatus set-up between the reaction container and the gas collection system.

Calcium Carbonate. The chemical compound calcium carbonate is composed of calcium, carbon and oxygen. A simplified equation for its formation would be the addition of calcium, oxygen and carbon dioxide to form CaCO3, the chemical formula for calcium carbonate. A major source of the compound is marine organisms such as coral, shellfish and mollusks, which use it to construct their shells, or skeleton-like casing.
