Abstract: A novel electrometric titration method-oscillographic coulometric titration is proposed,in which the oscillographic indication technique developed previously by one of the authors of this paper is used to indicate the end point of titration. Some examples of titration in redox system are given and briefly discussed.The results show that this method has the advantages of direct visual end point, simple manipulation and high sensitivity.

Key words: oscillographic coulometric titration, oscillographic titration, coulometric titration
