Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%. Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule.
Nitric acid is a powerful oxidizer, which will dissolve a very small quantity of gold, forming gold(III) ions (Au 3+). The hydrochloric acid provides a ready supply of chloride ions (Cl −), which react with the gold ions to produce tetrachloroaurate(III) anions ([AuCl 4] −), also in solution. The reaction with hydrochloric acid is an ...
Commonly used mineral acids are sulfuric acid (H 2 SO 4), hydrochloric acid (HCl) and nitric acid (HNO 3); these are also known as bench acids. [1] Mineral acids range from superacids (such as perchloric acid) to very weak ones (such as boric acid). Mineral acids tend to be very soluble in water and insoluble in organic solvents.

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.
Peroxynitrous acid (HNO 3) is a reactive nitrogen species (RNS). It is the conjugate acid of peroxynitrite (ONOO −).It has a pK a of approximately 6.8. It is formed in vivo from the diffusion-controlled reaction of nitrogen monoxide (ON •) and superoxide (O •−
Nitrogen acid may refer to: Nitric acid, HNO 3; Nitrous acid, HNO 2; Hyponitrous acid, H 2 N 2 O 2; or the less common nitrogen species: Nitroxyl, HNO; Nitroxylic ...
It is the mercury(II) salt of nitric acid HNO 3. It contains mercury(II) cations Hg 2+ and nitrate anions NO − 3, and water of crystallization H 2 O in the case of a hydrous salt. Mercury(II) nitrate forms hydrates Hg(NO 3) 2 ·xH 2 O. Anhydrous and hydrous salts are colorless or white soluble crystalline solids that are occasionally used as ...
