Many physicochemical processes can exhibit various forms of non-linear
dynamics, which have been widely investigated in the oscillatory
reaction Bray-Liebhafsky, too. The stoichiometry of this reaction
corresponds to the hydrogen peroxide decomposition to water and
oxygen in an acidic environment, in the presence of iodate ions as a
catalyst. During this reaction an oscillatory change of the intermediate
species concentration, along with a cascade change in the hydrogen
peroxide concentration and oxygen removal can be obtained. By
selecting the experimental conditions, the simple periodic or complex
chaotic concentration changes can be generated. Concentration
oscillations are a consequence of alternating dominance of different
reaction pathways present in the reaction mechanism. Large extent of the
phenomena experimentally observed in the oscillatory reaction Bray-
Liebhafsky is well explained by the mechanistic model, investigated by
the Belgrade group over a many years....
