Q4. A 5.00 ml aqueous sample containing hydrogen peroxide was diluted to 25 mL and analyzed by titration with permanganate: 2Mn04- + SH202 + 6H+ → 502 + 2M22+ + SH2O The sample required 42.8 mL of 0.0175 M permanganate to reach the end point. What is the concentration of hydrogen peroxide in the original sample?
