Abstract Electrochemical impedance measurements in the anodic range were made in 0.1 and 1 M solutions of sodium bromide using a rotating platinum disc electrode. It has been shown that bromide is oxidized in a rapid transfer reaction accompanied by diffusion of a bromine intermediate species, which was thought to be bromine itself. At 1 M, a further reaction was observed involving formation of the tribromide ion Br 3 − in the vicinity of the electrode. In a second set of experiments, impedance was measured in the presence of isosorbide. The overall shape of the diagrams was unchanged, indicating that oxidation of isosorbide takes place essentially in the bulk of the solution and not on the electrode.
