SOLVED: A 25.00-mL volume of commercial hydrogen peroxide solution wasdiluted to 250.0 mL in a volumetric flask. Then 25.00mL of the diluted solution were mixed with 200.mL of water and 20.mL of 3 M H2SO4 andtitratedwith 0.02177 M KMnO4. Thefirst pink color was observed with 27.72 mL oftitrant. A blank prepared from water in place ofH2O2 required 0.07 mL togive visible pink color.Using the H2O2 reaction inthe Analytical Applications of Permanganate Titrations table(H2O2 O2(g) 2H 2e-) (Titr
