Rotating Ring-Disk Study of the Silver Electrode in Alkaline Solution

Abstract

Rotating ring‐disk electrodes have been used for observing the soluble products on charge and discharge of potential or current controlled silver disks in and . Limits on the solubility of higher valent silver species corresponding to formation and the oxygen evolution region are given. The relative surface concentration of for all disk conditions has been measured and related to existing solubility data, the polarization characteristics of silver, and the reaction mechanisms.
