“…This molecule may exist mostly in the form in which the nitrogen atoms are pentavalent, the free nitrogen electrons being tied up. This assumption is supported by the physical measurements of Penny and Sutherland (5).…”

The autoxidation of stannous chloride in acid solution has been studied extensively by Young (8), Filson and Walton (1), and Haring and Walton(2). The oxidation of sodium stannite in alkaline solution, however, has never been studied in detail. Miyamoto (3) states that a solution of sodium stannite is autoxidized rapidly and that suspended stannous hydroxide is oxidized very slowly. The object of the present investigation was to study the autoxidation of the stannite ion, with particular emphasis upon the inhibition of the oxidation.REAGENTS, APPARATUS, AND PROCEDURE Baker's "purified" stannous chloride was found to give the same results SUMMARY 1. The autoxidation of sodium stannite is much more rapid than is the case with stannous chloride.2. The reaction rate increases slightly with an increase in the alkalinity of the solution.3. Nitrogen compounds with unshared electrons inhibit the reaction, ammonia being the most effective. The less the steric hindrance about the nitrogen atom, the greater is its power to inhibit. 4. Induced oxidation indicates the formation of a highly reactive perstannate.

“…Another important specific of this molecule is the rotation of fragments around the O-O bond, only insignificantly limited by the low potential barrier (~ 4 kJ mol -1 ), so dihedral angle between the planes of OH-groups can vary from 90° to 180° [18].…”

Hydrogen peroxide is a key substance in the appearance of life and maintenance of the life-supporting conditions on the Earth. Electron transfer processes between H 2 O 2 and various reducers are of major interest for the environment, natural life, technology, etc. An overview of structure, proprieties and main reactions of hydrogen peroxide in model and real systems is presented. The authors try to find the answers to the following questions: why this substance has the unique and specific dual reduction-oxidation properties, what is the connection between its structure and reactions, what role it plays in the catalytic reduction processes occurring in the natural environment and technological systems, accompanied by the formation of intermediate compounds, active radicals, complete and partial charge transfer complexes, etc. The thermodynamic possibility of the synchronous two-electron transfer during the inner sphere reaction with the involvement of metal ion complexes capable of changing the valence by two units is discussed. The role of the partial charge transfer structures which combine the properties of the initial reagents and the expected reaction products is demonstrated. Such complexes can be decomposed both reversibly and irreversibly. In case when the single-electron transfer is thermodynamically preferable, the main oxidizing particle is OH-radical, capable to interact non-selectively with almost all the water-soluble organic substances. Special attention is paid to the photo initiation of peroxidase transformation processes. The results of our multi-annual research of these issues are reported.
