Abstract:

A rotating silver disc electrode in a sodium hydroxide solution containing sodium sulfide was used to study the anodic polarization, passivation, and cathodic polarization of silver sulfide films on the silver disc electrode. Anodic limiting currents are controlled by convective diffusion of sulfide ions at potentials more anodic than the equilibrium potential for silver sulfidesulfide ion. The anodic depolarization of silver by sulfide is diffusion limited until the deposited film develops an appreciable thickness. All silver sulfide produced during anodic polarization is quantitatively reduced to silver during a cathodic potential scan. Author
