Carbon dioxide is a colourless gas having a faint sharp odour and a sour taste. Industrially, it is recovered for numerous diverse applications from flue gases, as a by-product of the preparation of hydrogen for synthesis of ammonia, from limekilns, and from other sources. At ordinary temperatures, carbon dioxide is quite unreactive; At temperatures above 1,700 degrees Celsius, it partially decomposes into carbon monoxide and oxygen. Hydrogen or carbon also convert it to carbon monoxide at high temperatures. Ammonia reacts with carbon dioxide under pressure to form ammonium carbamate, then urea, an important component of fertilizers and plastics. Carbon dioxide is slightly soluble in water, forming a weakly acidic solution. This solution contains the dibasic acid called carbonic acid. Ignited magnesium continues to burn in carbon dioxide, but the gas does not support the combustion of most materials.
