please help with this question,
Thank you!

Hydrogen peroxide can act as either an oxidizing agent or a reducing agent, depending on the species present in solution. Write balanced half-reaction equations for each of the following: (a) H-Oz(aq) acting as an oxidizing agent in an acidic solution. Write the balanced half-reaction equation. Phases are optonal. H2O2(aq) + 2H+ +2e. (b) H-O2(ag) acting as a reducing agent in an acidic solution. Write the balanced half-reaction equation. Phases are optional. (c) A disproportionation reaction is one in which a single species oxidizes and reduces itself. Write the complete balanced equation for the disproportionation reaction of H202(aq) Phases are optional. 2H o l olel+2H.oli about us careers privacy policy terms of use contact us help pling Learning, Inc.

Explanation / Answer

H2O2(aq) + 2H^+ (aq) + 2e^- -------------> 2H2O(l)     

A substance which participate in reduction reaction is called oxidizing agent.

H2O2 is participate in reduction reaction . So H2O2 is oxidizing agent.

b.H2O2(aq)----------------> 2H^+ (aq)+ O2 + 2e^-

A substance which participate in oxidation reaction is called reducing agent.

H2O is participate in oxidation reaction . So H2O is reducing agent.

c. 2H2O2 --------------> 2H2O + O2 disproportionation reaction

H2O2 is participate is oxidation and reduction reaction.
