  2. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    Nitrite is an ambidentate ligand and can form a wide variety of coordination complexes by binding to metal ions in several ways. [2] Two examples are the red nitrito complex [Co (NH 3) 5 (ONO)] 2+ is metastable, isomerizing to the yellow nitro complex [Co (NH 3) 5 (NO 2)] 2+. Nitrite is processed by several enzymes, all of which utilize ...

  3. 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. [1] It is a strong oxidizer and may accelerate the combustion of ...

  4. 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.

  5. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrification. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.

  6. Nitrite test - Wikipedia

    en.wikipedia.org/wiki/Nitrite_test

    A positive test for nitrites in the urine is called nitrituria. This test is commonly used in diagnosing urinary tract infections (UTIs). A positive nitrite test indicates that the cause of the UTI is a Gram-negative organism, most commonly Escherichia coli. The reason for nitrites' existence in the presence of a UTI is due to a bacterial ...

  7. Nitrifying bacteria - Wikipedia

    en.wikipedia.org/wiki/Nitrifying_bacteria

    Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds. [1] Types include ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB).

  8. 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 ...

  9. Sodium nitrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrate

    Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats ...
