10 ml of H2O2 solution when reacted with KI solution produced 0.5 g of iodine. The percentage of purity of H2O2 (by volume) is ______%. | Shaalaa.com

SOLVED: Calculate the KI and H2O2 concentrations. Assume the density of the 15% m/m (mass percent) H2O2 is 1.065 g/mL. Report all values to three significant figures. Run Number Volume of 0.25M KI (mL) 0.00 1.00 2.00 3.00 4.00 [H2O2] Volume of 15% H2O2 (mL) 1.00 1.00 1.00 1.00 1.00 Volume of H2O (mL) 4.00 3.00 2.00 1.00 0.00 [KI] 1 2 3 4 5
