The correct Answer is:
To solve the question regarding the assertion and reason provided, we will analyze both statements step by step. ### Step 1: Analyze the Assertion **Assertion (A): SO₂ and Cl₂ are both bleaching agents.** - **Bleaching Agents**: A bleaching agent is a substance that can remove color from materials, often through oxidation or reduction processes. - **SO₂ (Sulfur Dioxide)**: When sulfur dioxide is dissolved in water, it can form sulfurous acid (H₂SO₃), which can release nascent hydrogen. This nascent hydrogen can reduce colored compounds, effectively bleaching them. - **Cl₂ (Chlorine)**: Chlorine, when dissolved in water, can form hydrochloric acid (HCl) and hypochlorous acid (HOCl). The hypochlorous acid can release nascent oxygen, which can oxidize and bleach colored materials. **Conclusion for Assertion**: Both SO₂ and Cl₂ act as bleaching agents due to their ability to release nascent hydrogen and nascent oxygen, respectively. Therefore, the assertion is **correct**. ### Step 2: Analyze the Reason **Reason (R): Both are reducing agents.** - **Reducing Agents**: A reducing agent is a substance that donates electrons to another substance, thereby reducing it while itself being oxidized. - **SO₂**: In the context of its bleaching action, SO₂ can act as a reducing agent because it can donate electrons (or nascent hydrogen) to reduce other substances. - **Cl₂**: Chlorine, on the other hand, typically acts as an oxidizing agent. When chlorine (Cl₂) reacts, it gains electrons (is reduced) and thus does not function as a reducing agent. Instead, it oxidizes other substances. **Conclusion for Reason**: While SO₂ can act as a reducing agent, Cl₂ does not; it acts as an oxidizing agent. Therefore, the reason is **incorrect**. ### Final Conclusion - The assertion is correct: SO₂ and Cl₂ are both bleaching agents. - The reason is incorrect: Both are not reducing agents. ### Answer - The correct option is that the assertion is true, but the reason is false. ---
