◦ 0.0300 M
◦ 0.149 M
◦ 1.35 M
◦ 6.7 M
◦ 0.522 M

Question 2

A 5.000 mL aqueous sample containing hydrogen peroxide was diluted to 25 mL and analyzed by titration with permanganate:

2 MnO4-(aq) + 5 H2O2(aq) + 6 H+(aq) → 5 O2(g) + 2 Mn2+(aq) + 8 H2O(l)

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?
◦ 0.150 M
