How does the Hydrogen Peroxide Test Kit, Model HYP-1 work?
Hydrogen Peroxide Test Kit, Model HYP-1 reaction
In the Hydrogen Peroxide Test Kit, Model HYP-1 (Product # 2291700) the sample is acidified and the reaction is catalyzed by the addition of the Ammonium Molybdate solution. The Sulfite 1 reagent is added to provide iodide and starch. The hydrogen peroxide is reduced by the iodide to produce water and free iodine. Sodium thiosulfate is then used to titrate the iodine to a colorless end point. Starch enhances the determination of the end point by producing a color change from dark blue to colorless. The amount of hydrogen peroxide in the sample is calculated from the quantity of sodium thiosulfate added.
