✦ Synopsis

The carbon paste electrode has been used for studying the stoichiometry of the electrochemical reduction of Pt(IV) and Pt(II) and of the electrochemical oxidation of Pt(I1) and platinum black in acidic media. The electrochemical reduction of PtO, in 2 M H,SO, and in HCl(2 M and 6 M) was also reported. The reduction of Pt(I1) to Pt(0) and the evolution of H, was found to occur at about the same potential of -200 mV in HCl. We have been able to verify the effect of chloride concentration on the oxido-reduction potential of some of these reactions. The potential range values obtained agree with those predicted from thermodynamic data for some reactions. Pt(II) in solid PtC& was found to behave differently from Pt(II) in the solution of PtCl,.

A method for the construction of carb'on paste electrodes (CPE) is described. Here ferrocene is used as the insoluble electroactive species, graphite powder as conductor and sulfuric acid as binder. The CPE thus prepared prevents ferrocenium ions from diffusing towards the bulk solutions. Voltammetr
