Standardization of EDTA by spectrophotometric titration, with metallic copper as standard.
The standardization of EDTA against electrolytically pure copper is described. The copper is dissolved and titrated spectrophotometrically with EDTA at pH 5.0 without an indicator. A relative standard deviation of 0.009% was achieved.
