Abstract: Study on the use of oscillographic voltemmetric titration with if-E curve in redox reaction is carried out. It is shown that if-E curve shifts in the electrode potential axis at the time when the peak of faradaic current of depolarizer appeasror disapears at the end point of titration.This indication technique is highly sensitive and directly visual.

Key words: cyclic derivative chronopotentiometry, if-E curve, redox titration
