CO2 High Purity Gases Carbonic Acid Gas Dry Ice For Food Processing
?
?
Description:
?
Carbon dioxide (chemical formula CO2) is a colorless and odorless gas vital to life on Earth. This naturally occurring chemical compound is composed of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth& acute;s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.[3] Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas

Chemical Properties
colourless odourless gas
?
General Description
An odorless, white solid. Can cause damaging frostbite. Noncombustible and nontoxic. Liquefies at -109°F. Can asphyxiate by displacement of air. Used as a refrigerant.
?
Air & Water Reactions
Water soluble. Forms carbonic acid, a mild acid in water
?
Fire Hazard
Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket.
