Gas description

Ammonia, ammonia, NH3, colorless gas. It has a strong pungent smell. Density 0.7710. Relative density 0.5971 (air =1.00). Easy to liquefy into colorless liquid. It can be liquefied under pressure at normal temperature (critical temperature 132.4 ℃, critical pressure 11.2 MPa, i.e. 112.2 atmospheric pressure). Boiling point -33.5 ℃. It is also easy to solidify into snow like solid. Melting point -77.75 ℃. Soluble in water, ethanol and ether. At high temperature, it will decompose into nitrogen and hydrogen, with reduction effect. It can be oxidized to nitric oxide in the presence of catalyst. It is used to produce liquid nitrogen, ammonia, nitric acid, ammonium salt, amine, etc. It can be directly synthesized from nitrogen and hydrogen. It can burn the mucous membranes of skin, eyes and respiratory organs. If people inhale too much, it can cause lung swelling and even death.
