What is the Difference Between Bleaching Action of SO2 and Cl2?
🆚 Go to Comparative Table 🆚The main difference between the bleaching action of SO2 and Cl2 lies in the chemical reactions involved in the process.
- SO2 Bleaching: The bleaching action of SO2 is a reduction chemical reaction. It removes oxygen gas from the colored component, causing the removal of color. However, the oxygen from the atmosphere slowly replaces the removed oxygen, causing the regain of the color. This makes the bleaching action of SO2 temporary.
- Cl2 Bleaching: The bleaching action of Cl2 is an oxidation chemical reaction. It proceeds through an oxidation process, which is more permanent than the reduction process involved in SO2 bleaching. Chlorine reacts with water to produce nascent oxygen, which acts as an oxidizer.
In summary, the bleaching action of SO2 is temporary and based on reduction, while the bleaching action of Cl2 is permanent and based on oxidation.

Comparative Table: Bleaching Action of SO2 vs Cl2
The bleaching action of SO2 and Cl2 differs in terms of the type of chemical reaction they undergo and their permanence. Here is a comparison between the two:
Parameter | Bleaching Action of SO2 | Bleaching Action of Cl2 |
---|---|---|
Type of Reaction | Reduction | Oxidation |
Permanence | Temporary | Permanent |
Removal of Color | Removes oxygen from the colored substance, making it colorless | Removes electrons from the substance, causing it to gain color |
Addition of Color | Oxygen from the atmosphere slowly replaces the removed oxygen, causing the color to return | Adds electrons to the substance, causing it to lose color |
In summary, the bleaching action of SO2 is a reduction reaction that results in temporary bleaching, while the bleaching action of Cl2 is an oxidation reaction that results in permanent bleaching.
