Influence of the MoO4 2- Ions on the Bray−Liebhafsky Oscillatory Reaction

The influence of the MoO4 2- ions on the Bray−Liebhafsky (BL) oscillatory reaction is described. The MoO4 2- ions affect the values of the parameters of the BL reaction; first of all, they decrease the induction period and the duration of oscillations, but they increase the average frequency of osci...

Description
Summary:The influence of the MoO4 2- ions on the Bray−Liebhafsky (BL) oscillatory reaction is described. The MoO4 2- ions affect the values of the parameters of the BL reaction; first of all, they decrease the induction period and the duration of oscillations, but they increase the average frequency of oscillations. A qualitative explanation of this influence is based on the Treindl−Noyes skeleton mechanism of the BL oscillatory reaction. The production of singlet oxygen (1O2) by the disproportionation of hydrogen peroxide catalyzed by molybdate ions, which is obviously quenched physically and/or chemically, may play a role too.
