Industrial Gases - Ammonia

Ammonia is a chemical compound, formed by the combination of nitrogen and hydrogen in molar proportions of 1 part N2 to 3 parts of H2. NH3 is a colorless gas that has a pungent, irritating odor. Soluble in water and lighter than air, it forms only a very small portion of the atmosphere. It is found in volcanic gases and is produced when organic materials decay. Ammonia is also known as alkaline air and volatile alkali.
NH3 is used extensively to manufacture fertilizers and a variety of nitrogen-containing organic and inorganic chemicals.
