摘要

Rachwalska~1 reported oscillations in redox potential at a Pt-electrode in the well-stirred, aqueous, batch system KBrO_3 and H_2SO_4. The KBtO_3 contained __0.02% Br~- impurity. We are concerned that the experimentally observed oscillations in redox potential result from some form of physical/chemical artifact and should be treated with care. The major cause of our concern is that we see no basis for their occurrence in homogeneous FKN~2 oxybromine chemistry. However, because we have no experimental evidence for our concern, we accept at face value the experimentally observed oscillations. The origin of these oscillations in homogeneous chemical dynamics is supported by Rachwalska~1 using oscillatory simula_tions based on the FKN chemistry, given below using the author's numbering and rate parameters.
