Question:
Which of the following equation depicts reducing nature of H2O2?
(i) 2[Fe(CN)6]4– + 2H++ H2O2 → 2[Fe (CN)6]3– + 2H2O
(ii) I2 + H2O2 + 2OH– → 2I– + 2H2O + O2
(iii) Mn2+ + H2O2 → Mn4+ + 2OH–
(iv) PbS + 4H2O2 → PbSO4 + 4H2O
Solution:
Option (ii) I2 + H2O2 + 2OH– → 2I– + 2H2O + O2 is the answer.
