In a limited range of concentration of the reactants, oscillatory changes of pH and iodide ion concentration are observed in the iodate - sulfite - thiourea system in a CSTR. These changes can be quantitatively described by the simultaneous solution of four empirical rate laws of the corresponding sub-systems (iodate-hydrogen sulfite, iodate-iodide, iodine-hydrogen sulfite, and iodine-thiourea), considering two equilibria (sulfite-hydrogen ion and iodine-iodide).
