Space-time self-organization phenomena in oxidation of various substrates by atmospheric oxygen in aqueous solutions

In the oxidation of a number of organic and inorganic substrates by atmospheric oxygen in solutions under various conditions, oscillations of potential and the formation of spatial structures have been observed. Chaotic oscillations of the potential of a point platinum electrode have been observed in a system in which the reaction mixture is stirred, in contrast to the situation without stirring, in which spatial structures are formed, almost always visually evident when a redox indicator is introduced into the system.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2474–2482, November, 1991.The author wishes to thank Academician K.
