Which of the following acts as both reducing and oxidising agents?

Options

  1. AH 2 S O 4
  2. BH N O 3
  3. CH 2 O 2
  4. DK M n O 4

Correct answer

C. H 2 O 2

Step-by-step solution

In ( a ) , ( b ) and d ; Sulphur, nitrogen and Mn are in their maximum oxidation state, so they can only be reduced and thus can act only as oxidising agent. ( c ) only H 2 O 2 will act as both. (i) In case of oxidising agent H 2 O 2 itself get reduced: e.g., (ii) In case of reducing agent H 2 O 2 itself get oxidise
