Abstract: Oscillopolarographic titrations are usually carried out on Hg or Pt electrode using the appearance or disappearance of the incisions to indicate the end point of titration. This requires the reagent to give oscillopolarogram with sensitire incision. This paper reports that oscillopolarographic titrations can be carried out on Pt electrodes using the sudden change of the whole oscillogram (increase or decrease in size, shift in position) to indicate the end point. This is very common in redox titrations. The titrations of Cu2+with EDTA, Cl-with AgNO3and many neutralization titrations as well as redox titrations can be carried out in this way.
