Ammonia is an azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. It has a role as a NMR chemical shift reference compound, a metabolite, a neurotoxin, a nucleophilic reagent, a mouse metabolite, an EC 3.5.1.4 (amidase) inhibitor and a refrigerant. Ammonia solutions (containing more than 35% but not more than 50% ammonia) appears as a clear colorless liquid consisting of ammonia dissolved in water. Corrosive to tissue and metals. Although ammonia is lighter than air, the vapors from a leak will initially hug the ground.
