What is ammonia? Ammonia, also known as azane, is a chemical compound made of molecules which each contain one atom of nitrogen and three atoms of hydrogen. The molecular structure of ammonia is NH3. At ordinary room temperature and pressure, ammonia is a colourless gas which is lighter than air.
In attempting to understand the rationale used to measure ammonia, it is important to review some of the physical properties of the compound. Ammonia (NH3) is a colorless, acrid-smelling gas at room temperature and pressure. It easily dissolves in water and ionizes to form NH4+ as follows: NH3 + H2O ââ NH4++ OH-.
