Nitric oxide (NO) was first identified by Joseph Priestley in the late 18th century, originally seen as merely a toxic byproduct of combustion and an environmental pollutant. Its … See more

In commercial settings, nitric oxide is produced by the oxidation of ammonia at 750–900 °C (normally at 850 °C) with platinum as catalyst in the Ostwald process:
4 NH3 + 5 O2 → 4 NO + 6 H2O
The uncatalyzed See more

Acid rain deposition
Nitric oxide reacts with the hydroperoxyl radical (HO 2) to form nitrogen dioxide (NO2), which then … See more

With di- and triatomic molecules
Upon condensing to a liquid, nitric oxide dimerizes to dinitrogen dioxide, but the association is weak … See more

Nitric oxide concentration can be determined using a chemiluminescent reaction involving ozone. A sample containing nitric oxide is mixed with a large quantity of ozone. … See more

NO is a gaseous signaling molecule. It is a key vertebrate biological messenger, playing a role in a variety of biological processes. It is a bioproduct in almost all types of organisms, including bacteria, plants, fungi, and animal cells.
