Participation of oxygen in the catalysed and uncatalysed bromate oscillators

Simultaneous recording of potential and current oscillations in the Belousov-Zhabotinsky system provides valuable information regarding the course of the reaction. The negative current due to the step involving the production of bromine with the participation of oxygen has been confirmed by the absence of negative current in a deaerated solution. Further confirmation is obtained from the stationary potential measurements. © 1997 CECRI.
