For commercial purposes chromium is plated mostly from aqueous chromic acid baths. Because of problems including the technical difficulties (i. e. , low current efficiency, high cathode current densities, the relative toxicity of hexavalent chromium), extensive work has been conducted in recent years in order to develop trivalent chromium electrolytes. The purpose of this study is the investigation of the electrodeposition of metallic chromium from chromium (III) acetate. Such a study enables the determination of potentials for which the plating process can occur and, hence, may be useful for further, more detailed investigations.
