An objective document of polarographic study is the polarographic curve, that is, a curve visualizing the processes occurring in the course of electrolytic polarization of the dropping mercury electrode . In the case of the common voltage -controlled (or, with three-electrode systems potential -controlled, or " potentiostatic ") electrolysis, the polarographic curve is a current -voltage (or current-potential) curve showing the dependence of the current, passing through the system, on the voltage applied to the electrodes, or on the
