Liquid ammonia, also known as anhydrous ammonia, is a colorless liquid. Ammonia, as an important chemical raw material, is widely used. For convenient transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. Liquid ammonia is widely used in industry, and it is corrosive and easily volatile, so its chemical accident rate is quite high.

Density of liquid ammonia/:

Liquid ammonia is a colorless liquid with a strong pungent odor and is easily vaporized into gaseous ammonia. Density 0.617g/cm3; The boiling point is -33.5 ℃, and below -77.7 ℃, it can become a colorless crystal with a foul odor.

The use of liquid ammonia:

Mainly used for the production of Xiao acid, urea, and other chemical fertilizers, it can also be used as raw materials for pharmaceuticals and pesticides. It can be used as an ammonification raw material for organic chemical products and also as a refrigerant. Liquid ammonia can also be used for silk finishing of textiles. The lone electron pairs in NH3 molecules tend to form coordination bonds with other molecules or ions, generating various forms of ammonia complexes.

Liquid ammonia is a great solvent, and due to the polarity of its molecules and the presence of hydrogen bonds, it shares many physical properties with water. Some reactive metals can displace hydrogen and generate hydroxides from water, making it less likely to displace hydrogen in liquid ammonia. But liquid ammonia can dissolve metals to form a blue solution. This metal liquid ammonia solution can conduct electricity and slowly decompose to release hydrogen gas, with strong reducibility.
