Sodium nitrite works by creating methemoglobin, where the iron atom at the center of the heme group is in the oxidized ferric (Fe 3+) state, which binds with cyanide with greater affinity than its binding to the cytochrome C oxidase, and thus removes it from blocking the metabolic function of mitochondria.
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.
Nitrates and nitrites extend shelf life, [citation needed] help kill bacteria, produce a characteristic flavor and give meat a pink or red color. [17] Nitrite (NO − 2) is generally supplied by sodium nitrite or (indirectly) by potassium nitrate. Nitrite salts are most often used to accelerate curing and impart a pink colour. [18]
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 ...
Nitrosation is typically performed with nitrous acid, formed from acidification of a sodium nitrite solution. Nitrous acid is unstable, and high yields require a rapid reaction rate; NO + synthon transfer is catalyzed by a strong nucleophile, such as (in increasing order of efficacy) chloride, bromide, thiocyanate, or thiourea.
Curing salt is used in meat processing to generate a pinkish shade and to extend shelf life. [1] It is both a color agent and a means to facilitate food preservation as it prevents or slows spoilage by bacteria or fungus. Curing salts are generally a mixture of sodium chloride (table salt) and sodium nitrite, and are used for pickling meats as ...

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 ...
