Nitration, III

This can be prepared by the controlled reduction of a nitrite (nitrate(III)) or nitrate. Cautious heating of ammonium nitrate gives dinitrogen oxide by an internal oxidation-reduction process ...

The application of VSEPR theory to triatomic molecules is exemplified by considering water, carbon dioxide, xenon difluoride and a trio of connected species the nitronium ion, N02+, nitrogen dioxide and the nitrite [or nitrate(III)] ion, N02. ... 

The reduction potential for the nitrate(V)/nitrate(III) couple in acid solution of +0.94 V indicates from the limited data in Table 6.12 that nitrate(V) ion in acidic solution is a reasonably good oxidizing agent. However, nitric acid as an oxidant usually functions in a different manner, with the production of brown fumes with a metal (e.g. copper) or a metal sulfide (e.g. FeS2). The brown fumes consist of N204 (brown gas) and its monomer N02 (colourless gas). Concentrated nitric acid consists of about 70% of the acid in an aqueous solution. In such a solution there is some dissociation of the nitric acid molecules to give the nitronium ion, N02, which represents the primary oxidizing species ...

Recent studies have shown that LMCT excited states of the [Femedta] complexes can be quenched not only by molecular oxygen and other electron acceptors, eg chromate(VI), but also by electron donors, such as free EDTA, sulphate(IV), nitrate(III), or alcohols the suggested mechanism is presented in Figure 9.12 [22, 23],... 

N-Nitroso compounds were detected in low concentrations in air, water, and food, particularly meat products to which nitrate(III) had been added and certain fish products. NDMA was detected in urban air samples. The presence of N-nitroso...

Quenching [Fe°(edta )(H20)] by electron donors leads in a deoxygenated medium to the regeneration of the edta ligand from the edta radical and formation of the reduced Fe(II) complex and oxidized donor molecule (D = aliphatic alcohol, sulfate (IV), nitrate(III) or even extraneous edta ligand) ... 

Similarly, there are nitrate(V) and nitrate(III) multi-atom ions. The former is the one we ve come across, NOj, with an oxidation number of — 1, because -1-5 (for the nitrogen) -i- [3 X (—2)] = —1. This is usually simply called nitrate.

The ether group in dmgs such as econazole nitrate (III) and miconazole nitrate (IV) is susceptible to oxidation. The process involves removal of hydrogen from the C-H bonds in the a-position to the oxygen to produce radicals, which further degrade to a-hydroperox-ides and evenmally to aldehydes, ketones, alcohols and carboxylic acids. 

With the temperature increase in the range 298-333K, there is observed the increase in Au(III) ions sorption compared to that of Pd(II) ions. The sodium nitrate(III) and thiourea solutions were used as eluents. Sodium nitrate(III) (2 M, pH 4.7) desorbs 75% of Pd(II) practically not washing out Au(III) from the ion exchanger, whereas thiourea (0.5 M, [H ] 0.1 M) enables almost quantitative recovery of gold(III) containing trace amounts of palladium (II) ions.

Two other inorganic ions that are stabilized by resonance and described by a series of symmetrical resonance structures are the nitrate(iii) ( nitrite ) ion, N02, and the nitrate(v) ( nitrate ) ion, N03 (Figure 14-46). Curly arrows may be used to show the movement of electron pairs to generate resonance structures.
