Nitrogen hyponitrous acid

There is also considerable current environmental interest in hyponitrite oxidation because it is implicated in the oxidation of ammonia to nitrite, an important step in the nitrogen cycle (p. 410). Specifically, it seems likely that the oxidation proceeds from ammonia through hydroxylamine and hyponitrous acid to nitrite (or N2O).

Page 129. The gas which is thus employed as a test for the presence of oxygen, is the binoxide of nitrogen, or nitrous oxide. It is a colourless gas, which, when brought in contact with oxygen, unites with it, forming hyponitric acid, the red gas referred to.

As shown in the previous chapter, besides N20, a soft nitrogen-containing acid (pH 3-A suggested to be hyponitrous acid H2N202) is present in the products of molecular nitrogen oxidative fixation with hydrogen peroxide. 

Between nitric acid and ammonia, or between nitric acid and free nitrogen, stand the lower oxidation products of nitrogen, viz., nitrous and hyponitrous acids, or the lower oxides of nitrogen, NO2, N2O3, NO and N2O. In the same way nitric acid substitution products are reduced to ammonia substitution products, i.e., nitro compounds are reduced to amino compounds.

Nitrogen also forms hyponitrous acid, H2N2O2, in which N is in the +1 oxidation state, as well as hyponitrite salts snch as Na2N202. 

SCF calculations have been carried out on the molecule HNO ( nitrosyl hydride ) and its isomer HON ( nitrogen hydroxide ). " The system is found to have a low-lying triplet state, which is expected to aid in the dimerization to hyponitrous acid, H2O2N2.
