Individually proposed kinetic models of the key subsystems of the chlorite-thiosulfate reaction, such as the hypochlorous acid-chlorite, tetrathionate-chlorite, and tetrathionate-chlorine dioxide reactions, have been unified to be able to describe all the main characteristics of these systems simultaneously. A complex 38-step kinetic model is composed in which the subsystems are coupled by the necessary short-lived intermediates and such species that is products or reactants in one system but transients in the other. Such a cross-coupling between the individual systems as well as the sound agreement between the measured and calculated absorbance-time profiles in 367 experimental curves strongly validates the proposed kinetic model.
