We investigated the dynamic behavior between the redox potential and the solution viscosity and density of the BZ reaction by the systematic variation of the mixing level of the solution and the solution viscosity and density. The mixing level was controlled by the stirrer bar speed, and the solution viscosity and density was changed by the addition of the Polyoxyethylen (10) octylphenyl Ether (Triton X-100). This study has revealed that the three types of the oscillations with the phase difference appear depending on the mixing level and the solution viscosity and density of theBZ reaction. It has also become clear that the criticalmicellization concentration (cmc) play an important role in the behavior of the oscillation of the solution viscosity and density.
