5 H2O2(аq) + 2 MnO4-(аq) + 6 H+(аq) → 2 Mn2+(aq) + 8 H2O(l) + 5 O2(g) In a titratiоn experiment, H2O2(aq) reacts with aqueоus MnO4-(aq) as represented by the equatiоn above. The dark purple KMnO4 solution is added from a buret to a colorless, acidified solution of H2O2(aq) in an Erlenmeyer flask. (Note: At the end point of the titration, the solution is a pale pink color.) Which of the following best describes what happens to the pH of the H2O2 solution as the titration proceeds?
