An amperometric study of the reactions of copper(I) and copper(II) oxides with barium peroxide in surfactant suspensions

Abstract

A study was made of the arnperometric titration of the reaction between barium peroxide and copper(1) and copper(n) oxides. It was shown that it was possible to titrate a solid with a solid in surfactant suspensions. The studies were made in aqueous and acetonitrile suspensions containing cationic surfactants. End points were obtained at molecular ratios of BaOz to CuO of 1 : 1, 1 : 3, and 1 : 5; and molecular ratios of BaOz to CuzO of 1 : 1 and 2: 1. It was postulated that the reactions involving CuO wereThe reactions involving Cu20 were postulated to be
