What is ammonia? Ammonia, also known as azane, is a chemical compound made of molecules which each contain one atom of nitrogen and three atoms of hydrogen. The molecular structure of ammonia is NH3. At ordinary room temperature and pressure, ammonia is a colourless gas which is lighter than air.
Some chemical/physical properties of ammonia are: 1  At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor. 2  In pure form, it is known as anhydrous ammonia and is hygroscopic (readily absorbs moisture).3  Ammonia has alkaline properties and is corrosive. Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. 2  Ammonia gas is easily compressed and forms a clear liquid under pressure. 3  Ammonia is usually shipped as a compressed liquid in steel containers.
