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.
Tin(IV) nitrate reacts with trifloroacetic acid anhydride to yield (NO 2 +) 2 [Sn(OOCCF 3) 6 2−] which is a nitronium salt. With trifluoroacetic acid a similar compound solvated with trifluoroacetic acid is produced. [6] It also reacts with acetic anhydride or acetic acid to produce tin(IV) acetate and with nitric oxide to produce tin(IV ...
Titanium nitride (TiN) is a refractory solid exhibiting extreme hardness, thermal/electrical conductivity, and a high melting point. [13] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15]
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Tin(II) fluoride is added to some dental care products [111] as stannous fluoride (SnF 2). Tin(II) fluoride can be mixed with calcium abrasives while the more common sodium fluoride gradually becomes biologically inactive in the presence of calcium compounds. [112] It has also been shown to be more effective than sodium fluoride in controlling ...
The nitrides of the alkaline earth metals that have the formula M 3 N 2 are however numerous. Examples include beryllium nitride (Be 3 N 2), magnesium nitride (Mg 3 N 2), calcium nitride (Ca 3 N 2), and strontium nitride (Sr 3 N 2). The nitrides of electropositive metals (including Li, Zn, and the alkaline earth metals) readily hydrolyze upon ...
Nitrite is also a common ligand that can coordinate in five ways. The most common are nitro (bonded from the nitrogen) and nitrito (bonded from an oxygen). Nitro-nitrito isomerism is common, where the nitrito form is usually less stable. [19] Fuming nitric acid contaminated with yellow nitrogen dioxide
