One method of determining the concentration of hydrogen peroxide (H2O2) in a solution is through titration with the iodide ion. The net ionic equation for this reaction is
H2O2 + 21° +2H+ + 12 + 2H2O
A 28.70 mL sample of a hydrogen peroxide solution is found to react completely with 25.57 mL of a
0.1500 M Kl solution. What is the concentration of hydrogen peroxide in the sample?
