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.
Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
NO 3 − + 2 H + + 2 e − → NO 2 − + H 2 O (Nitrate reductase) NO 2 − + 2 H + + e − → NO + H 2 O (Nitrite reductase) 2 NO + 2 H + + 2 e − → N 2 O + H 2 O (Nitric-oxide reductase) N 2 O + 2 H + + 2 e − → N 2 + H 2 O (Nitrous-oxide reductase) The complete process can be expressed as a net balanced redox reaction, where nitrate ...
3 → NO 3 + O 2. This reaction can be performed also in the solid phase or water solutions, by irradiating frozen gas mixtures, flash photolysis and radiolysis of nitrate salts and nitric acid, and several other methods. [1] Nitrogen trioxide is a product of the photolysis of dinitrogen pentoxide N 2 O 5, chlorine nitrate ClONO 2, and ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

Nitrogen assimilation is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compounds present in the environment. Organisms like plants, fungi and certain bacteria that can fix nitrogen gas (N 2) depend on the ability to assimilate nitrate or ammonia for their needs.
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).
