Home > Ostwald process

The Ostwald process is a commercial process, invented by Wilhelm Ostwald, used to produce nitric acid. Following production from the Haber process, Ammonia is heated with a catalyst ( platinum) to form nitric oxide that is then oxidized to yield nitrogen dioxide, which in turn reacts with water to yield nitric acid and nitric oxide:
4 NH3 + 5 O2 → 4 NO + 6 H2O
2 NO + O2 → 2 NO2
4 NO2 + O2 + 2 H2O → 4 HNO3(aq)

Fixing Nitrogen into ammonia and nitric acid was a key development in the production of fertilisers and explosives. Previously sources of Nitrogen had been Guano and ChileThe word chile may also refer to Chilli pepper. The Republic of Chile is a republic located on the southwestern coast of South America. It is a long and narrow piece of land between the Andes mountains and the Pacific Ocean. It shares borders with Argenti saltpeter (NaNO3).
