The Strength of a Hydrogen Peroxide, H₂O₂, Solution Can Be $\rarr$

Multiple Choice

The strength of a hydrogen peroxide, H₂O₂, solution can be determined by titration with permanganate solution. The reaction is:
2 MnO₄^-(aq) + 5 H₂O₂(aq) + 6 H⁺ $\rarr$ 5O₂(g) + 2 Mn²⁺(aq) + 8 H₂O If it required 80.0 mL of 0.0220 molar MnO₄^-(aq) solution to titrate 5.0 mL of a H₂O₂(aq) solution, what is the molarity of the H₂O₂(aq) solution?

A) 0.14 M
B) 0.18 M
C) 0.35 M
D) 0.62 M
E) 0.88 M
