A hydrogen peroxide solution is analyzed by adding a slight excess of standard KMNO, solution and back-titrating the unreacted KMNO, with standard Fe+ solution. A 0.587-g sample of the H,O, solution is taken, 25.0 mL of 0.0215 M KMNO, is added, and the back-titration requires 5.10 mL of 0.112 M Fe?+ solution. What is the percent H,O, in the sample?
