Description and Uses

Carbon dioxide is a colorless, odorless, noncombustible gas present throughout the atmosphere and is an essential compound for life on Earth. It is found on other planets in the solar system. Mars’s icecaps are primarily frozen carbon dioxide and Venus’s atmosphere is mostly carbon dioxide. Carbon dioxide occurs naturally as approximately 0.03% v/v of the atmosphere.Solid carbon dioxide, also known as dry ice, is usually encountered as white-colored pellets or blocks.

Carbon dioxide has several major uses: Solid carbon dioxide, dry ice, is used as a refrigerant. Another major use of carbon dioxide is in the soda industry. Soda is sodium carbonate monohydrate (Na2CO3? H2O). Other forms of soda include washing soda, which is sodium carbonate decahydrate (Na2CO3? 10H2O), and baking soda, which is sodium bicarbonate (NaHCO3).Carbon dioxide is used as a gas in fire extinguishers, as an inflation gas for flotation devices, and as a propellant (for example in air guns). In recent years, the use of carbon dioxide as a supercritical fluid in green chemistry applications has increased. A supercritical fluid is a fluid with a temperature and pressure above its critical point.
