A 25.00-mL volume of commercial hydrogen peroxide 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 3 M H2SO4 and titrated with 0.02177 M KMnO4. The first pink color was observed with 27.72 mL of titrant. A blank prepared from water in place of H2O2 required 0.07 mL to give visible pink color.
Using the H2O2 reaction in the Analytical Applications of Permanganate Titrations table (H2O2 <---> O2(g) + 2H+ + 2e-) (Titrate in 1 M H2SO4.), find the molarity of the commercial H2O2.
