| Abstract: | The kinetics of cerium(III) ion catalyzed Br(V) oxidation of oxalic acid in the presence of HClO4/H2SO4 and mercury(II)-a bromide removing ion, exhibits second order each in [br(V)] and [acid], 0.4 and zero order in [Ce(III)]. However, the kinetic behavior of oxalic acid is anomalous with –0.7, zero and 1.4 order. The chemistry underlying the phenomena is discussed.
