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. ...


Examples

See category for a bigger list. Nitrous acid weak monobasic acid known only in solution and in the form of nitrite salts. ... Sodium nitrite, with chemical formula NaNO2, also called nitrous acid, sodium salt, is used as a color fixative and preservative in meats and fish. ... The chemical compound methyl nitrite is an Alkyl nitrite. ...


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. ... 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. ... 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. General Name, Symbol, Number sodium, Na, 11 Chemical series alkali metals Group, Period, Block 1, 3, s Appearance silvery white Atomic mass 22. ... 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. ...

Nitrite - Koi Club of San Diego (654 words)
Nitrite, NO -N, measured in parts per million (ppm), is the second chemical measurement made to determine the "health" of the biologic converter.
A low nitrite reading combined with a significant ammonia reading indicates the ammonia-nitrite biologic converter action is not established, while a low ammonia reading with a detectable nitrite reading indicates that the nitrite-nitrate bacterial conversion activity is not yet working.
Source: Nitrite is produced by autotrophic bacteria combining oxygen and ammonia in the bio-converter and to a lesser degree on the walls of the pond.
Drugs - Amyl, Butyl or Isobutyl Nitrite, Nitrates, Poppers (664 words)
Amyl/butyl nitrite (poppers) is a powerful drug that can give you an almighty burst of dizzy energy for a couple of minutes.
The rush kicks in immediately, and for a few moments you'll feel like the bass drum has got inside your head, the lights have been turned up to a zillion watts and your heart is attempting a solo flight.
First produced in 1857 as a treatment for angina, amyl nitrite evaporates at room temperature.
