The correct Answer is:
To analyze the statements regarding the reaction of hydrogen peroxide (H₂O₂), we will break down the process step by step. ### Step 1: Understanding Disproportionation Reaction A disproportionation reaction is a specific type of redox reaction in which a single substance is both oxidized and reduced, resulting in two different products. ### Step 2: Writing the Reaction The reaction given is: \[ \text{H}_2\text{O}_2 \rightarrow \text{H}_2\text{O} + \frac{1}{2} \text{O}_2 \] ### Step 3: Assigning Oxidation States Next, we need to determine the oxidation states of the elements involved in the reaction. 1. In H₂O₂ (hydrogen peroxide): - The oxidation state of hydrogen (H) is +1. - Let the oxidation state of oxygen (O) be \( x \). - The equation for H₂O₂ becomes: \[ 2(+1) + 2x = 0 \] \[ 2 + 2x = 0 \] \[ 2x = -2 \] \[ x = -1 \] - Therefore, the oxidation state of oxygen in H₂O₂ is -1. 2. In H₂O (water): - The oxidation state of oxygen is -2. - The equation for H₂O becomes: \[ 2(+1) + x = 0 \] \[ 2 + x = 0 \] \[ x = -2 \] 3. In O₂ (elemental oxygen): - The oxidation state of oxygen is 0. ### Step 4: Identifying Oxidation and Reduction Now, we can identify the changes in oxidation states: - Oxygen in H₂O₂ changes from -1 (in H₂O₂) to -2 (in H₂O) - this is a reduction. - Oxygen in H₂O₂ changes from -1 (in H₂O₂) to 0 (in O₂) - this is an oxidation. ### Step 5: Conclusion on Disproportionation Since H₂O₂ is both oxidized and reduced in this reaction, it is indeed a disproportionation reaction. Therefore, **Statement 1 is correct**. ### Step 6: Analyzing Statement 2 Statement 2 claims that H₂O₂ can act as both an oxidizing agent and a reducing agent. - As an oxidizing agent, H₂O₂ can oxidize other substances while itself being reduced (as seen in the formation of H₂O). - As a reducing agent, H₂O₂ can reduce other substances while itself being oxidized (as seen in the formation of O₂). ### Step 7: Conclusion on Statement 2 Since H₂O₂ can act as both an oxidizing agent and a reducing agent, **Statement 2 is also correct**. ### Final Conclusion Both statements are true: - **Statement 1**: H₂O₂ to H₂O + (1/2)O₂ is an example of a disproportionation reaction. - **Statement 2**: H₂O₂ can act as an oxidizing as well as a reducing agent.
