Abstract: This paper reports the use of the oscillographic indication technique in the kinetic method of analysis.The product resulted from the kinetic reaction in KBrO₃-KBr-HCl system is used as a titrant and the zero current oscillographic bipotentiometric titrationtechnique is used to indicate the end point. The results obtained with KBrO₃-KBr-HCl system show that this method can be used to determine reducing substances such as As(Ⅲ),ascorbic acid,etc.and has a sensitivity about 10^-6-10^-7mol/dm³.This method is directly visible and rapid and needs only simple equipment.

Key words: Oscillographic indication technique, Oscillographic bipotentiometry Kinetic method of analysis
