Abstract

The reaction between H2O2 and KSCN catalyzed by CuSO4 exhibits three different types of bistability as a function of flow rate in a continuous flow stirred tank reactor at 25°C. Two steady states and one oscillatory state are involved. The system is one of the few examples in which oscillations can appear in batch configuration as well. The color, the potential of a Pt electrode, and the rate of oxygen gas evolution oscillate for a wide range of reagent concentrations. The chemistry which accounts for the observed behavior is discussed briefly.
