10mL of a commercial peroxide solution measured with a volumetric pipet was diluted to 100mL in a volumetric flask and mixed thoroughly 25 mL of the diluted peroxide was titrated. Assume that the diluted peroxide solution had a density of 1.000 gmL-1.
volume of diluted hydrogen peroxide 25.00 mL
molarity of the potassium permanganate 1.992x10-2 M
potassium permanganate solution initial reading 1.17 mL, final reading 26.09 mL
