Answer 2

Hydrogen peroxide is  an oxidizing agent for the reaction  H₂O₂ + 2HI → I₂ + 2H₂O and reducing agent  for the reaction

HOCl + H₂O₂ → H₃O + + Cl⁻ + O₂.

Explanation:

Oxidizing agent  

• Redox reaction, the reactant which removes electrons from other reactants.
• These electrons takes for itself, which is reducing and gaining electrons.it is an electron acceptor.

Reducing agent

• In redox reaction, the reactant lose electrons so it is oxidizing.
• Formic acid, earth metals and sulfite compounds are examples for reducing agents.
• It lose electrons and other substances are reduced. Its oxidation state increased.

• In this reaction the oxidation number of H2O2 is -1 and reduced to H2O is -2. Hence it is decreased and acts as oxidizing agent.
• In this reaction the oxidation number of H2O2 is -1 and raised to O2 is 0. Hence it is increased and acts as reducing agent.
