Nitrite is a nitrogen-containing anion with the formula NO− 2, which can be produced industrially or by acid-base reactions. It has various applications, such as food preservation, pharmaceuticals, and explosives, and can undergo oxidation, reduction, and addition reactions.
Nitrites in urine can indicate a urinary tract infection (UTI), which is usually treated with antibiotics. Learn how nitrites are tested, diagnosed, and prevented in this article.
Nitrite-positive urine is a sign of a possible urinary tract infection (UTI) caused by bacteria. Learn how a urinalysis detects nitrites in urine, how antibiotics treat UTIs and how to prevent them.
nitrite, any member of either of two classes of compounds derived from nitrous acid. Salts of nitrous acid are ionic compounds containing the nitrite ion, NO -2, and a positive ion such as Na + in sodium nitrite (NaNO 2). Esters of nitrous acid are covalent compounds having the structure R―O―N―O, in which R represents a carbon-containing combining group such as ethyl (C 2 H 5) in ethyl ...

Nitrite is a symmetric anion composed of 1 nitrogen and 2 oxygen atoms. It is used for curing meat, as a vasodilator, and in the digestive system. Learn more about its structure, properties, uses, and FAQs.
Sodium nitrite is used as a food preservative and in reddening meats. Many nutritionists recommend the avoidance of foods that contain sodium nitrite because it can undergo chemical reactions that produce nitrosamines, which are known carcinogens. Sodium nitrite is also used in dyeing textiles, bleaching fibers, photography, metal coatings, and the manufacture of rubber chemicals. In medicine ...
