Abstract

Abstract: An oscillopolarograp Hic titration method for the determination of sodium chloride is described in the paper Sodium chloride was titrated by silver nitrate in 0. I mol/l NH4Ac solution Then the excess of silver nitrate reacted with potassium dichromate.The disappecrance of the incission of dichromate on dE/dt-E curves indicated the end point of titrotion The available experimental conditions were proposed The method was directly used to determine sodium chloride in soy sauce and paste without decolorization.

Key words: OscillopolarograpHic, Titration, Sodium Chloride, Sauce
