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.
The Griess test is an analytical chemistry test which detects the presence of nitrite ion in solution. One of its most important uses is the determination of nitrite in drinking water . The Griess diazotization reaction, on which the Griess reagent relies, was first described in 1858 by Peter Griess .
the nitrate ion, a nitrogen atom bound to three oxygen atoms, (e.g. nitroglycerin, ANFO) the nitrite ion, a nitrogen atom bound to two oxygen atoms [citation needed] Most commercially used explosives include the nitrate ion or the nitro group. II. −N=N−, −N − =N + =N − −
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. The reason for nitrites ...
The color intensity of the resulting solution is then measured by a colorimeter and checked against a calibration curve to determine the nitrite ion concentration. [ 4 ] To analyze nitrate concentrations quantitatively, the sample is first passed through a copper-cadmium column to reduce the nitrate ions quantitatively to nitrite ions, and the ...
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.
Sodium hyponitrite is a solid ionic compound with formula Na 2 N 2 O 2 or (Na +) 2 [ON=NO] 2−. [1]There are cis and trans forms of the hyponitrite ion N 2 O 2− 2.The trans form is more common, but the cis form can be obtained too, and it is more reactive than the trans form.
In chemistry, hyponitrite may refer to the anion N 2 O 2− 2 ([ON=NO] 2−), or to any ionic compound that contains it. In organic chemistry, it may also refer to the group −O−N=N−O−, or any organic compound with the generic formula R 1 −O−N=N−O−R 2, where R 1 and R 2 are organic groups. [1]
