Ar impedance measurements have been made at the vitreous carbon-sodium polysulphide (liquid) interphase at a temperature of 350°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
