✦ Synopsis
flask and allow to stand for 20 min. Titrate with 0.1 N sodium thiosulphate solution to the starch end-point (for small concentrations of hydrogen peroxide, 0.01 N thiosulphatc can bc used with little deterioration in the end-point).

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
