•A 25.00 mL volume of commercial hydrogen peroxide (H2O2) solution was diluted to 250.0 mL in a volumetric flask. Then 25.00 mL of the diluted solution were mixed with 200 mL of water and 20 mL of H2SO4 and titrated with 0.02123 M KMnO4. The first pink color was observed with 27.66 mL of titrant. A blank prepared from water in place of H2O2 required 0.04 mL to give visible pink color. Find the molarity of the commercial H2O2.
