ON THE POSSIBILITY OF STUDYING ADSORPTION OF HYDROXYL IONS AT METALS BY THE CONTACT ELECTRORESISTANCE METHOD

The scarcity of data on the adsorption of hydroxyl ions at metals is s hown to be caused by the absence of experimental methods sensitive to their adsorption. A technique for in situ measuring the contact electr oresistance (CER) of metals in electrolytes is briefly described. The results of measuring CER at gold, platinum, silver copper, and iron ar e presented. The conclusion is drawn that the CER method may be used t o study adsorption of hydroxyl ions at other metals and alloys.
