In order to analyze a commercial hydrogen peroxide solution by the procedure described in this experiment, you must first dilute the commercial peroxide solution with distilled water. For example, 10Ml of a commercial peroxide solution measured with a volumetric pipet was diluted to 100ml in a volumetric flask and mixed thoroughly. 25.00ml of diluted peroxide was titrated. Assume that the diluted

peroxide solution had a density of 1.000g/ml-1
Volume of diluted hydrogen peroxide solution, ml 25.00
Molarity of the potassium solution 1.992x10-2
Potassium permanganate solution
initial buret reading 1.17
final buret reading 26.09
