Hydrogen peroxide in its reaction with KIO₄ and NH₂OH respectively, is acting as a

A reducing agent, oxidising agent
B reducing agent, reducing agent
C oxidising agent, oxidising agent
D oxidising agent, reducing agent

Verified Solution

Answer & Solution

Correct Answer

(A) reducing agent, oxidising agent

Step-by-step Solution

Detailed explanation

K l O_{4} + H_{2} O_{2} \to K l O_{3} + H_{2} O + O_{2}

In this reaction

H_{2} O_{2}

act as reducing agent

N H_{2} O H + 3 H_{2} O_{2} \to H N O_{3} + 4 H_{2} O

In this reaction

H_{2} O_{2}

act as oxidising agent.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
