[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
Nitrogen trioxide or nitrate radical is an oxide of nitrogen with formula NO 3, consisting of three oxygen atoms covalently bound to a nitrogen atom. This highly unstable blue compound has not been isolated in pure form, but can be generated and observed as a short-lived component of gas, liquid, or solid systems.
Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO.It is one of the principal oxides of nitrogen.Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).
Erythrosine, also known as E127 and Red No. 3, is an organoiodine compound, specifically a derivative of fluorone. It is a red-pink dye used for food coloring, cosmetics, hair coloring, pet products, and diverse industrial colorings. [2] [3] It is the disodium salt of 2,4,5,7-tetraiodofluorescein. [2]
The relatively complicated formula - [Cr(H 2 O) 6](NO 3) 3 •3H 2 O - betray a simple structure of this material. The chromium centers are bound to six aquo ligands, and the remaining volume of the solid is occupied by three nitrate anions and three molecules of water of crystallization. [3]
The FDA has said it has been actively reviewing Red No. 3’s approval following a petition filed by a coalition of organizations, including the CSPI, asking the FDA to revoke the additive’s ...
No mineral of the ideal Cu(NO 3) formula, or the hydrates, are known. Likasite, Cu 3 (NO 3)(OH) 5 ·2H 2 O and buttgenbachite, Cu 19 (NO 3) 2 (OH) 32 Cl 4 ·2H 2 O are related minerals. [21] [22] Natural basic copper nitrates include the rare minerals gerhardtite and rouaite, both being polymorphs of Cu 2 (NO 3)(OH) 3.
