Description
A colorless, strong smelling gas that is the fifth highest volume chemical produced in the United States. Ammonia was also the first complex molecule to be identified in interstellar space. Gaseous ammonia was first isolated by Joseph Priestly in 1774. It is used for chemical synthesis and in the manufacture of explosives and fertilizers. Ammonia has also been used as a vapor phase neutralizing/alkalizing agent where it neutralizes effectively but provides no residual alkaline reserve (Book and Paper catalog). Ammonia is most often sold as an aqueous solution of Ammonium hydroxide,
