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.
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 ...
An electrode in which oxidation takes place is called an anode while in that which reduction takes place is called cathode. This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same. Red cat: Reduction at cathode; An ox: Anode for oxidation. [32]
H 2 N 2 O 2 + 2 H + + 2 e − ⇌ N 2 + 2 H 2 O; E 0 = +2.65 V. Oxidation reactions usually result in the formation of the nitrate ion, with nitrogen in oxidation state +5. For example, oxidation with permanganate ion can be used for quantitative analysis of nitrite (by titration): 5 NO − 2 + 2 MnO − 4 + 6 H + → 5 NO − 3 + 2 Mn 2+ + 3 H 2 O
The series is now published by John Wiley & Sons, Inc., [2] which acquired Hungry Minds (the new name for IDG Books as of 2000) in early 2001. [3] Various books in the series. Notable For Dummies books include: DOS For Dummies, the first, published in 1991, whose first printing was just 7,500 copies [4] [5]

The nitrate reductase of higher plants, algae, and fungi is a homodimeric cytosolic protein with five conserved domains in each monomer: 1) an Mo-MPT domain that contains the single molybdopterin cofactor, 2) a dimer interface domain, 3) a cytochrome b domain, and 4) an NADH-binding domain that combines with 5) an FAD-binding domain to form the ...
