This method is suitable for measuring aqueous solutions of H2O2 ranging from 0.25 to 70 wt.%. Even though it made the reaction go faster, the substance itself didn’t change during the reaction. It is so called "Elephant Toothpaste" because the foam is so much, and come out from beaker just like squeezing out too… Interferences Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997. Potassium permanganate - now more commonly known as potassium manganate(VII) - reacts with acidified hydrogen peroxide. I would just like to know what the theoretical relationship is … Hydrogen peroxide is injurious to cells because it attacks unsaturated fatty acids (lipids) found in cell membranes and consequently cells produce a powerful catalyst, catalase, that decomposes H2O2 (Keusch). Therefore the titration reaction will not be unique. Natural Decomposition of Hydrogen Peroxide. Chemical reaction. With the peroxide solution in excess, we added 10ml vinegar and 10ml of different concentrations of permanganate and timed the reaction. Quartz particles (>90% SiO2, –1 +0.15 mm) were used as solids in the experiments. Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.
