Which of the following cannot be oxidized by H₂O₂?
Correct answer: B. O3
- A. KI + HCl
- B. O3
- C. PbS
- D. Na2SO3
Explanation
Ozone (O₃) is a much stronger oxidizing agent than hydrogen peroxide (H₂O₂). Therefore, H₂O₂ cannot oxidize O₃; instead, H₂O₂ would act as a reducing agent in a reaction with ozone.
