Nitrogen compounds oxoacids

The redox chemistry of nitrogen compounds in aqueous solution is illustrated in the Frost diagram in Fig. 1 (see Topic E5 for construction and use). All oxides and oxoacids are strong oxidizing agents, and all oxidation states except -3, 0 and +5 are susceptible to disproportionation. The detailed reactions are, however, mostly controlled by kinetic rather than thermodynamic considerations. In conjunction with oxidizable groups, as in ammonium nitrate NH4N03 or in... 

This section deals with the binary compounds that nitrogen forms with metals, and then describes the extensive chemistry of the hydrides, halides, pseudohalides, oxides and oxoacids of the element. The chemistry of P-N compounds is deferred until Chapter 12 (p. 531) and S-N... 

Nitrogen forms numerous oxoacids, though several are unstable in the free state and are known only in aqueous solution or as their salts. The principal species are summarized in Table 11.12 of these by far the most stable is nitric acid and this compound, together with... 

The important compounds of nitrogen with hydrogen are ammonia, Irydrazine, and hydrazoic acid, the parent of the shock-sensitive azides. Phosphine forms neutral solutions in water reaction of phosphorous halides with water produces oxoacids without change in oxidation number. 

Nitrogen forms oxides in each of its integer oxidation states front +1 to +5 the properties of the oxides and oxoacids are related to the oxidation number of nitrogen in the compound. 

Figure 8.13 The central role of transdeamination in metabolism of amino adds and further metabolism of the oxoacids in the liver. The box contains the reactions for conversion of the amino acids to their respective oxoacids. Processes are as follows (1) digestion of protein in the intestine and absorption of resultant amino acids, (2) degradation of endogenous protein to amino acids (primarily but not exclusively muscle protein), (3) protein synthesis, (4) conversion of amino acid to other nitrogen-containing compounds (see Table 8.4), (5) oxidation to CO2, (6) conversion to glucose via gluconeogenesis, (7) conversion to fat.

Many of the salts of nitrogenous bases (particularly of high nitrogen content) with oxoacids are unstable or explosive. There are separate group entries below and individually indexed compounds ... 

Oxygen The many known nitrogen oxides have unusual structures, all with some degree of multiple compounds bonding. Oxocations and oxoacids can be formed, of which nitric acid is the most important.
