摘要

In a stirred sulfuric acid solution containing initially potassium bromidic, cerium sulfate, and malonic acid, the concentrations of bromide ion and of cerium (IV) undergo repeated oscillations of razor proportions. The concentrations of these species have been followed potentiometrically and the detailed mechanism of the reaction has been elucidated, When the solution contains sufficient bromide ion, BrO3 is reduced to Br2 by successive oxygen atom transfers (2-equivalcnt redox processes), and the malonic acid is brominates by an penalization mechanism.
