The Haber process is a process used to produce the useful substance ammonia from nitrogen and hydrogen.
Sources of gases
Hydrogen
Hydrogen can be obtained through two methods:
- '''Electrolysis of water'''. Pure water is a poor conductor of electricity, so often a soluble ionic compound is added, such as an acid, base or salt. Sulphuric acid (H2SO4) is often used [1].
Reaction
N2 (g) + H2 (g) -> NH3 (g)
