AbstractIn the present work, an improved titration method, called the potassium permanganate titration, was developed to quantitatively measure the mass of copper(I) oxide in the corrosion products formed on copper. This method can accurately measure the mass of copper(I) oxide on the copper surface, and the error is within +/- 3%, which was calibrated by microgravimetry. The accuracy of this improved method is higher than other current commonly used methods for determining the amount of copper(I) oxide. The effect of oxygen on the accuracy of the measurements was studied, which determined whether the operating environment of each step was in an aerobic or anaerobic environment. It was verified that ammonia can act as the solvent to completely dissolve the corrosion products without damaging the copper matrix. The amount of the copper(I) oxide formed on copper surface was also measured using this method. The potassium permanganate titration is particularly applicable to determine the amount of copper(I) oxide on the copper exposed in atmospheric environments in the absence of chloride ions.
