Problem

Under certain conditions, H2O2 can act as an oxidizing agent; under other conditions, as a reducing agent. What is the best theoretical explanation for this?

(A) H2O2 is a good bleaching agent.

(B) Peroxides are stronger oxidizing agents than are oxides.

(C) H2O2 will decolorize KMnO4 solutions in the presence of an acid and will turn black lead sulfide to a white compound.

(D) An atom within a compound can sometimes attain more stable electronic structure gaining or by losing electrons.
