Description
Colorless gas with a pungent, suffocating odor. [Note: Shipped as a liquefied compressed gas. Easily liquefied under pressure.]
ChEBI: Ammonia is an azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. It has a role as a nucleophilic reagent, a neurotoxin, a metabolite, an EC 3.5.1.4 (amidase) inhibitor, a refrigerant and a mouse metabolite. It is an azane, a mononuclear parent hydride and a gas molecular entity. It is a conjugate base of an ammonium. It is a conjugate acid of an azanide.
Characteristics

-0.7
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. Long term exposure to low concentrations or short term exposure to high concentrations may result in adverse health conditions from inhalation. Prolonged exposure of containers to fire or heat may result in their violent rupturing and rocketing.
