Electrolysis of Potassium Iodate/Hydrogen Peroxide in Briggs-Rauscher Oscillation
The experiment has been attempted. Electrolysis through the use of copper electrodes in fact "kills" the reaction. This means that the whole system is immediately turned dark-blue, and eventually made more clearer, and eventually light blue indicating the presence of copper ions.

It is suspected that not only is the sulphate ion electrolysed, but perhaps the copper iodizes the potassium and other compounds.
