Question

Identify the set of molecules which act as bleaching agents only by oxidation

• A. \( SO_2, O_3 \)
• B. \( O_3, NO \)
• C. \( Cl_2, O_3 \)
• D. \( SO_2, O_3, Cl_2 \)

Hint:

Bleaching agents that act by oxidation break down colored molecules through the addition of oxygen or the removal of electrons.

Answer 1

The Correct Option is C

Bleaching agents like \( O_3 \) (ozone) and \( Cl_2 \) (chlorine) act as oxidizing agents. Both ozone and chlorine bleach by oxidation, breaking down colored compounds into colorless compounds. Thus, the correct answer is \( Cl_2, O_3 \).
