Abstract

Oxidation states of copper in Cu-O-M-X(M-In, Cu, X=Cl, NO3) and Y-Ba-Cu-O systems have been determined by redox titration. After highly oxidized copper was directly reacted with excess ferrous ions in acidic solution, residual ferrous ions have been titrated with standardized bichromate solutions.
