In the closed system of iodate, hydrogen sulfite, and thiosulfate, high-amplitude, greatly damped pH oscillation occurs in unusually narrow concentration ranges of reactants. A semiquantitative description of the kinetic curves has been made in terms of the empirical rate laws of the subsystems by making allowance for cross effects. The skeleton model is closely related to the Lotka model, the archetype of chemical oscillators. A possible mechanism is suggested to give an account of experimental findings.
