  2. Nitrous acid - Wikipedia

    en.wikipedia.org/wiki/Nitrous_acid

    Nitrous acid (molecular formula H N O 2) is a weak and monoprotic acid known only in solution, in the gas phase, and in the form of nitrite (NO − 2) salts. [3] It was discovered by Carl Wilhelm Scheele, who called it "phlogisticated acid of niter".

  3. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    The nitrite ion has the chemical formula NO − 2.Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature.

  4. Potassium nitrite - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrite

    Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2.It is an ionic salt of potassium ions K + and nitrite ions NO 2 −, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water.

  5. Hyponitrous acid - Wikipedia

    en.wikipedia.org/wiki/Hyponitrous_acid

    There are two possible structures of hyponitrous acid, trans and cis.trans-Hyponitrous acid forms white crystals that are explosive when dry.In aqueous solution, it is a weak acid (pK a1 = 7.21, pK a2 = 11.54), [2] and decomposes to nitrous oxide and water with a half life of 16 days at 25 °C at pH 1–3:

  6. 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.

  7. Ammonium nitrite - Wikipedia

    en.wikipedia.org/wiki/Ammonium_nitrite

    Ammonium nitrite forms naturally in the air and can be prepared by the absorption of equal parts nitrogen dioxide and nitric oxide in aqueous ammonia. [1]It can also be synthesized by oxidizing ammonia with ozone or hydrogen peroxide, or in a precipitation reaction of barium or lead nitrite with ammonium sulfate, or silver nitrite with ammonium chloride, or ammonium perchlorate with potassium ...

  8. Nitrosyl-O-hydroxide - Wikipedia

    en.wikipedia.org/wiki/Nitrosyl-O-hydroxide

    Nitrosyl-O-hydroxide (molecular formula H O O N) is an isomer of nitrous acid, which has been experimentally observed in the gas phase. [2]HOON contains the longest oxygen-oxygen bond thus far observed in any known molecule, measured to be 1.9149 angstroms.

  9. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
