\( S O_{2} \) and \( C l_{2} \) both are used as bleaching agent. Factors that cause bleaching are respectively:
- A. \( H \) (that causes reduction), \( O \) (that causes oxidation)
- B. \( O \) (that causes reduction), \( H \) (that causes oxidation)
- C. \( H \) (that causes oxidation), \( O \) (that causes reduction)
- D. \( O \) (that causes oxidation), \( H \) (that causes reduction)
Step-by-step solution
SO2 bleaches by reduction; in the presence of moisture, it produces nascent hydrogen which reduces colored compounds. Cl2 bleaches by oxidation; it produces nascent oxygen which oxidizes colored compounds.
