Abstract
Method for determination of zero charge potential at using of polarization of electrode by periodic current with reversed pulse and fast breakdown of polarizating circuit has been presented. It is shown that after electric circuit was broken a displacement of potentials in anodic and cathodic parts of cycle happens by going to meet each other. The potential, at which the displacement of corresponding curves occurs, corre- sponds to zero charge point. This method can be used in investigation of redox reactions, adsorption and de- sorption of active-on-surface substances during electrolyze process; for correcting composition of electro- lytes in labs and factories.
