Liquid Ammonia

Brief Overview
Ammonia (NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compounds in the atmosphere. Low concentration of ammonia has no significant effect on human beings. However, exposure to high concentration of gaseous ammonia can result in lung damage and even death, thus protective measures should be taken during the operation.
Manufacturing Process
There are several ways of manufacturing liquid ammonia:
Method 1: Presently, ammonia is produced by the Haber-Bosch process which involve industrial hydrogen reacting with atmospheric nitrogen under high temperature and pressure in the presence of catalyst.
Method 2: For small-scale lab synthesis, ammonia can also be manufactured through the heating of urea and Ca(OH)2 together.
