Chromium (III) (2-20 mg) is determined by reaction with excess of EDTA and backtitration with a standard copper (II) solution to a catalytic end-point. The indicator reaction is the copper (II) -catalyzed autodecomposition of hydrogen peroxide, which is observed biamperometrically. For 10 mg of chro
