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.
A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions. They are mixed-anion compounds , and they are mixed-valence compounds .
The lighter isotope of nitrogen, 14 N, is preferred during denitrification, leaving the heavier nitrogen isotope, 15 N, in the residual matter. This selectivity leads to the enrichment of 14 N in the biomass compared to 15 N. [27] Moreover, the relative abundance of 14 N can be analyzed to distinguish denitrification apart from other processes ...
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.
2 NO + 3 + NO − 3 ⇌ H 2 O + [NO 2] + + [NO 3] −. Two hydrates, HNO 3 ·H 2 O and HNO 3 ·3H 2 O, are known that can be crystallised. It is a strong acid and concentrated solutions are strong oxidising agents, though gold, platinum, rhodium, and iridium are immune to attack.
NO 2 also reacts with ozone to form nitrate radical NO 2 + O 3 → NO 3 + O 2. During the daytime, NO 3 is quickly photolyzed back to NO 2, but at night it can react with a second NO 2 to form dinitrogen pentoxide. NO 2 + NO 3 (+M) → N 2 O 5 (+M). N 2 O 5 reacts rapidly with liquid water (in aerosol particles or cloud drops, but not in the ...
Being the conjugate base of a strong acid (nitric acid, pK a = -1.4), nitrate has modest Lewis basicity.Two coordination modes are common: unidentate and bidentate.Often, bidentate nitrate, denoted κ 2-NO 3, is bound unsymmetrically in the sense that one M-O distance is clearly bonding and the other is more weakly interacting.

Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.
