A closed region of bistability exitst in the plot of input stream concentrations of ferroin and bromate. The bromate-ferroin-bromide systems exhibits bistability and high amplitude oscillations over a broad range of concentrations. As a first approximation a revised Oregonator type model extended by reactions of ferroin and ferriin describes the system. However, further reactions have to be taken into consideration for a quantitative description.

The behaviour of the reacting oscillating systems depends to a certain extent on the catalyst applied. Both the rate of heat evolution and the rate of accumulation of monobromomalonic acid are periodic. The heat of the cerium-catalysed Belousov oscillating reaction is 130 ± 5 kJ mol–1 bromate.
