  2. 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 ...

  3. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    Infobox references. Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [ 5 ]

  4. Liebermann reagent - Wikipedia

    en.wikipedia.org/wiki/Liebermann_Reagent

    Liebermann reagent. The Liebermann reagent named after Hungarian chemist Leo Liebermann (1852-1926) is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of potassium nitrite and concentrated sulfuric acid. [ 1 ][ 2 ] 1 g of potassium nitrite is used for every 10 mL of sulfuric ...

  5. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    Sodium nitrite is an effective corrosion inhibitorand is used as an additive in industrial greases,[5]as an aqueous solution in closed loop cooling systems, and in a molten state as a heat transfer medium. [6] Food additive and preservative. [edit] Sodium nitrite is used to speed up the curingof meat,[7]inhibit the germination of Clostridium ...

  6. 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. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.

  7. Caustic pencil - Wikipedia

    en.wikipedia.org/wiki/Caustic_pencil

    Typical caustic pencil with detail of dried, oxidized, and inactive chemical. A caustic pencil (or silver nitrate stick) is a device for applying topical medication containing silver nitrate and potassium nitrate, used to chemically cauterize skin, providing hemostasis or permanently destroying unwanted tissue such as a wart, skin tag, aphthous ulcers, or over-production of granulation tissue. [1]

  8. 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". Nitrous acid is used to make diazonium salts from amines.

  9. Sodium nitroprusside - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitroprusside

    Sodium nitroprusside (SNP), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [ 3 ] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [ 3 ]
