Gas introduction
Ammonia is an inorganic compound with a chemical formula of NH3 and a molecular weight of 17.031. Under standard conditions, its density is 0.771g/L and its relative density is 0.5971 (air = 1.00). It is a colorless gas with a strong pungent odor. Ammonia can turn moist red litmus paper blue and produce a small amount of hydroxide ions in water, which is weakly alkaline. It can be liquefied by pressurizing at room temperature (critical temperature 132.4℃, critical pressure 11.2 MPa, i.e. 112.2 atmospheres), with a boiling point of -33.5℃. It is also easily solidified into a snow-like solid, with a melting point of -77.75℃, and is soluble in water, ethanol and ether. It decomposes into nitrogen and hydrogen at high temperatures and has a reducing effect. Ammonia can be oxidized into nitric oxide in the presence of a catalyst. Ammonia is often used to make liquid nitrogen, ammonia water, nitric acid, ammonium salts and amines. Ammonia can be produced directly from nitrogen and hydrogen. It can burn the skin, eyes, and mucous membranes of the respiratory organs. If people inhale too much, it can cause lung swelling and even death.
