Role of hydrogen peroxide in the below reactions is respectively (CBSE AIPMT 2014) I. H O O H O 2O -> II. H O Ag O 2Ag H O O ->
A.oxidising in I and reducing in II
B.reducing in I and oxidising in II
C.reducing in I and II✓ Correct
D.oxidising in I and II
Explanation
In the reaction, 2 2 3 2 2 H O O H O 2O -> Since, H2O2 reduced O3 into H2O, thus at behaves as an reducing agent. Further in the reaction, H2O2 reduces Ag2O into metallic silver (Ag)(as oxidation number is reducing from +1 to 0). Thus, H2O2 behaves as a reducing agent.
