It is not so easy to replace hydrogen in liquid ammonia. But liquid ammonia can dissolve the metal to produce a blue solution. This metal liquid ammonia solution can conduct electricity and slowly decompose to liberate hydrogen gas, which has strong reducibility.
For example, liquid ammonia solution of sodium: The liquid metal ammonia solution is blue, conductive and has strong reducibility because the "ammonia electrons" are generated in the solution.
As an important chemical raw material, liquid ammonia is usually used to obtain liquid ammonia by pressurizing or cooling gaseous ammonia for the convenience of transportation and storage. Liquid ammonia is mostly stored in pressure-resistant steel cylinders or steel tanks, and cannot coexist with acetaldehyde, acrolein, boron and other substances.
Liquid ammonia is widely used in industry, is corrosive and easy to volatilize, so its chemical accident rate is very high. Liquid ammonia is mainly used to produce nitric acid, urea and other chemical fertilizers, and can also be used as a raw material for medicines and pesticides.
