"The reaction between tetrathionate and hydrogen peroxide forms a part of some pH-oscillators based on oxidation of thiosulfate. The kinetics of this reaction have been studied using a pH-meter in the pH range of about 8 to 10.5. Experimental data were evaluated by the method of initial reaction rates combined with assumption of instantaneously equilibrated acid-base reactions. The rate-determining step was found to be first order with respect to tetrathionate, hydrogen peroxide and OH- ions concentrations. The waveform of measured pH during the course of reaction indicates that thiosulfate is a probable intermediate, because typical characteristics of obtained time-curves are very similar to those for oxidation of thiosulfate. In the alkaline solution no clear catalytic effect of Cu2+ was observed." . . "Tatransk\u00E9 Matliare" . .
