Abstract
A new technique has been developed for the measurement of the potential of zero charge (PZC) of solid electrodes. The technique utilizes the repulsion between identically charged double layers (DL) and electrodes. This potential (or charge) dependent repulsion is shown to affect the time of contact (TOC) between two electrodes when one is struck by the other. It is shown that the TOC is a minimum at the PZC. Measurements on gold electrodes in perchloric acid solutions showed minima in the TOC near the potential +0.01V SCE. In sodium iodide solutions the minimum of TOC was shifted cathodically corresponding to the expected shift of the PZC resulting from specific adsorption of iodide. This technique, after several improvements, is suggested for measuring the PZC of solid electrodes.
