Ar impedance measurements have been made at the vitreous carbon-sodium polysulphide (liquid) interphase at a temperature of 350Β°C. Molten Na2S3 and Na2S5 were employed. The impedance data confirm that the reaction is purely diffusion-controlled at relatively low overpotentials and that a film IS pre

Previous voltaiumetric work[1] on the anodic evolution of sulphur has been complemented by a microscopic study of the surfaces of working anodes in a thin-layer cell . The observations confirm the earlier conclusions that the anodic process initially involves the oxidation of polysulphide anions to
