Abstract: The present paper covers the mechanism of incision formation in oscillopolarograms about aniline and fluorescein sodium as oscillopolarographic neutralization indicators.The incision change of fluorescein sodium is due to oxido-reduction and that of aniline due to absorption of the indicators at the polarized electrode.

Key words: Oscillopolarographic titration indicators, Fluorescein sodium, Aniline, Mechanism of incision
