HCK Monotest COD 160

Measurement of the changing of the color of a solution of Potassium Dichromate in Sulfuric Acid, due to the reduction of Hexavalent Chromium (yellow) to Trivalent Chromium (green), due to the effect of oxidizable substances contained in the water, in the presence of a catalyst.
