Question

Which of the following equation depicts the oxidizing nature of H O ? 2 2 - 2 2 + 2 2 2 2 2 2 2 2 3 + - 2 2 2 2 - - 2 2 2 2

(A) 2I  + H O  + 2H → I  + 2H O
(B) CI  + H O  → 2HCI + O
(C) HOCl+ H O  →H O + Cl  +O
(D) I  + H O  + 2OH  → 2I  + 2H O + O

Prashant Kotian · Accepted Answer

Correct answer: D) I  + H O  + 2OH  → 2I  + 2H O + O. Here, the oxidation state of the Iodine atoms is changing from -1 to 0 and that of the oxygen atoms is changing from -1 to -2. Hence, H O acts as an oxidizing agent.
