Question

When H2O2 is oxidised by a suitable oxidant, one of the products is :

• A. O2–
• B. HO2–
• C. OH–
• D. O2

Answer 1

Answer: (D)

O2

Answer 2

H2O2 when oxidised in acidic or basic medium it produces O2

2MnO4– + 6H+ + 5H2O2 $\longrightarrow$2 Mn2+ + 8H2O + 5O2 (acidic medium)

2MnO–4 + 3H2O2 $\longrightarrow$2MnO2 + 3O2 + 2H2O (basic medium)
