Silver oxalate films have been formed on silver electrodes by polarizing them slightly cathodically in dilute aqueous solutions containing Ag+ ions and dimethyl oxalate. The solutions were supersaturated with silver oxalate which was produced as a result of the hydrolysis of dimethyl oxalate and was sparingly soluble. The supersaturation was maintained during the film formation.
The potential of the silver electrode with silver oxalate formed at a very low current density, showed a linear response to the oxalate ion concentration between 10-4 and 10-1 M.
