  2. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    A nitrite ester. In organic chemistry, alkyl nitrites are esters of nitrous acid and contain the nitrosoxy functional group. Nitro compounds contain the C–NO 2 group. Nitrites have the general formula RONO, where R is an aryl or alkyl group. Amyl nitrite and other alkyl nitrites have a vasodilating action and must be handled in the laboratory ...

  3. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).

  4. Sodium nitrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrate

    A small amount of the nitrate added to meat as a preservative breaks down into nitrite, in addition to any nitrite that may also be added. The nitrite then reacts with protein-rich foods (such as meat) to produce carcinogenic NOCs (nitroso compounds). NOCs can be formed either when meat is cured or in the body as meat is digested. [20]

  5. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    Sodium nitrite is an inorganic compound with the chemical formula Na N O 2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. From an industrial perspective, it is the most important nitrite salt.

  6. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    The nitrate anion is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. [citation needed] This charge results from a combination formal charge in which each of the three oxygens carries a ...

  7. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    The difference is attributed to the similarity in size between nitrate (NO − 3) and carbonate (CO 2− 3) ions and the fact that the potassium ion (K +) is larger than sodium (Na +) and calcium (Ca 2+) ions. [34] In the room-temperature structure of potassium nitrate, each potassium ion is surrounded by 6 nitrate ions.

  8. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N. 2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]

  9. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N 2, a colourless and odourless diatomic ...
