(A) HOCl + H 2 O 2 → H 3 O + + Cl - + O 2 (B) I 2 + H 2 O 2 + 2 OH - → 2 I - + 2 H 2 O + O 2 Choose the correct option.

Options

  1. AH 2 O 2 act as oxidizing and reducing agent respectively in equations ( A ) and ( B ) .
  2. BH 2 O 2 acts as oxidising agent in equations ( A ) and ( B ) .
  3. CH 2 O 2 acts as reducing and oxidising agent respectively in equations ( A ) and ( B ) .
  4. DH 2 O 2 acts as reducing agent in equations ( A ) and ( B ) .

Correct answer

D. H 2 O 2 acts as reducing agent in equations ( A ) and ( B ) .

Step-by-step solution

In ( A ) reduction of HOCl occurs, so it will be an oxidising agent hence H 2 O 2 will be a reducing agent. In ( B ) reduction of I 2 occurs, so it will be an oxidising agent and H 2 O 2 will be a reducing agent.
