Question:
Which of the following equations depict the oxidising nature of H2O2?
(i) 2MnO4– + 6H+ + 5H2O2 → 2Mn2+ + 8H2O +5O2
(ii) 2Fe + 2H + H2O2 → 2Fe2+ + 2H2O +O2
(iii) 2I– + 2H+ + H2O2 → I2 + 2H2O
(iv) KIO4+ H2O2 → KIO3 + H2O + O2
Solution:
Option (iii) 2I– + 2H+ + H2O2 → I2 + 2H2O is the answer.
