Nitrous oxide  [ Return towards  Other gases  ]

On Earth, it occurs naturally in soil and oceans. It is produced by the combustion of organic or fossils matters, particularly in industry. The massive use of Nitrogen-based chemical fertilizers has contributed to increase the level of nitrous oxide found in soil.

It was discovered in 1776 by Joseph Priestley.

More about the history of nitrous oxide

Nitrous oxide is generally produced from ammonium nitrate that, above 210°C, breaks down into steam and gaseous nitrous oxide.

Another method involves the direct oxidation of ammonia (NH₃) in the presence of a catalyst.

At normal temperature and pressure, nitrous oxide is a colorless, odorless gas. Dissolved in water, it tastes slightly sweet.

Because of its chemical formula, it is a source of Oxygen that may be useful in electronics, for depositions in the gaseous phase, and as an oxidant to improve gas-fueled engines performance.

Because of its analgesic properties, it is also used in healthcare during anesthesia and to treat pain during minor surgical procedures.
