Oscillations in the bromate system with malic acid as the substrate

The oscillation characteristics, investigated by potentiometry, of the bromate-Mn(II)/Ce(III)-malic acid system are presented. The induction period characteristic of the oscillatory system is analysed. The results are compared with the malonic acid and citric acid systems and are correlated with the difference in the rate of bromide production, proposed as the control intermediate. © 1980 Indian Academy of Sciences.
