Definition

The nitrite ion is NO₂⁻. An ion is an atom or group of atoms with a net electric charge. ...

A nitrite compound is one that contains this group, either an ionic compound, or an analogous covalent one. These may be considered salts or esters of nitrous acid. A magnified crystal of salt In chemistry, salt is a term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. ... General formula of an ester of a carboxylic acid. ... Nitrous acid weak monobasic acid known only in solution and in the form of nitrite salts. ...

Discussion

In inorganic chemistry, nitrites are salts of nitrous acid HNO₂. They contain the nitrite ion NO₂^-. Nitrites of the alkali and alkaline earth metals can be synthesized by reacting a mixture of nitrogen monoxide NO and nitrogen dioxide NO₂ with the corresponding metal hydroxide solution. Other nitrites are available through the reduction of the corresponding nitrates. Inorganic chemistry is the branch of chemistry concerned with the properties and reactions of inorganic compounds. ...

Nitrous acid weak monobasic acid known only in solution and in the form of nitrite salts. ... An ion is an atom or group of atoms with a net electric charge. ... The alkali metals are the series of elements in Group 1 (IUPAC style) of the periodic table, excluding hydrogen: that is, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). ... The alkaline earth metals are the series of elements in Group 2 (IUPAC style) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra) (not always considered due to its radioactivity and very short half-life). ... The chemical compound nitric oxide is a gas with chemical formula NO. It is an important signaling molecule in the body of mammals including humans, one of the few gaseous signaling molecules known. ... The chemical compound nitrogen dioxide (NO2) is a red or orange/brown gas with a characteristic sharp, biting odor. ... Hydroxide is a polyatomic ion consisting of oxygen and hydrogen: OH− It has a charge of −1. ... Reduction or reducing has several meanings: In mathematics, reduction is the process of manipulating a series of equations or matrices into a desired simpler format. ... In inorganic chemistry, nitrates are the salts of nitric acid. ...

Sodium nitrite is used for the curing of meat because it prevents bacterial growth and, in a reaction with the meat's myoglobin, gives the product a desirable dark red color. Because of the toxicity of nitrite (lethal dose of nitrite for humans is about 22 mg per kg body weight), the maximum allowed nitrite concentration in meat products is 200 ppm. Under certain conditions, especially during cooking, nitrites in meat can react with degradation products of amino acids, forming nitrosamines, which are known carcinogens.

Myoglobin is a single-chain protein of 153 amino acids, containing a heme (iron-containing porphyrin) group in the center. ... PPM can stand for more than one thing: Pages per minute, a measure of speed often used to market printers or photocopiers the Portable Pixmap file format the PPM compression algorithm (Prediction by partial matching) used in computer science Parts per million, a measure of concentration Portable People Meter peak... In chemistry, an amino acid is any molecule that contains both amino and carboxylic acid functional groups. ... Nitrosamines are carcinogenic chemical compounds of the chemical structure R2N-N=O. Nitrosamines are produced from nitrites and amines. ... In pathology, a carcinogen is any substance or agent that promotes cancer. ...

In organic chemistry, nitrites mean the esters of nitrous acid. They possess the general formula R-O-N=O, R being an aryl or alkyl group. Amyl nitrite is used in medicine for the treatment of heart diseases. Organic chemistry is the scientific study of the structure, properties, composition, reactions, and synthesis of organic compounds that by definition contain carbon. ... General formula of an ester of a carboxylic acid. ... In the context of organic molecules, aryl refers to any member of the set of functional groups or substituents that are derived from a simple aromatic ring. ... An Alkyl is a univalent radical containing only carbon and hydrogen atoms arranged in a chain. ... The chemical compound amyl nitrite (here referring to isoamyl nitrite) is an Alkyl nitrite. ...

Nitrites should not be confused with nitrates, the salts of nitric acid, or with nitro compounds, though they share the formula NO₂. The nitrite ion NO₂^- should not be confused with the nitronium ion NO₂⁺. In inorganic chemistry, nitrates are the salts of nitric acid. ...

Nitro compounds are organic compounds that contain one or more nitro functional groups (NO2). ... The nitronium ion, NO2+, is not stable enough to exist in normal conditions, but it is used extensively in the nitration of other substances. ...
