Abstract
We have studied the cathodic processes on a platinum electrode in ozonized sulfuric acid solutions of different concentrations. The kinetic parameters of corrosion processes have been determined. The cathodic processes on a platinum electrode in the presence of ozone are more intense by a factor of 1.5 than in the presence of oxygen. Ozone increases the possibility of chemical reaction with the help of generation of OH− ions. In addition, we have proposed a scheme for the action of ozone in acid media.
