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.
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 .
Sodium nitrate and nitrite are associated with a higher risk of colorectal cancer. [19] Substantial evidence in recent decades, facilitated by an increased understanding of pathological processes and science, exists in support of the theory that processed meat increases the risk of colon cancer and that this is due to the nitrate content.
Infobox references. Nitrate is a polyatomic ion with the chemical formula NO−. 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [1] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate .
UNII. M0KG633D4F. HX1032V43M. Sodium nitrite/sodium thiosulfate, sold under the brand name Nithiodote, is a fixed-dose combination medication used as an antidote for cyanide poisoning. [1] It contains sodium thiosulfate and sodium nitrite. [1] It is given by intravenous infusion into a vein. [1]
A nitrite test is a standard component of a urinary test strip. 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.
Chemical formula. NO3−. Molar mass. 62.005 g·mol −1. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Reactions of peroxynitrite leading to either apoptotic or necrotic cell death. Peroxynitrite (sometimes called peroxonitrite) is an ion with the formula ...
A common nitrate test, known as the brown ring test [2] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]
