The correct Answer is:
To solve the question, we need to analyze both statements provided and determine their correctness. ### Step-by-Step Solution: 1. **Analyzing Statement 1**: - The statement claims that copper is dissolved at the anode and deposited at the cathode when copper electrodes are used in a 1 M CuSO₄ (aq) solution. - In an electrochemical cell, the anode is where oxidation occurs, and the cathode is where reduction occurs. - When copper electrodes are used, the copper at the anode will oxidize (lose electrons) and dissolve into the solution as Cu²⁺ ions. The reaction at the anode can be represented as: \[ \text{Cu (s)} \rightarrow \text{Cu}^{2+} (aq) + 2e^- \] - At the cathode, Cu²⁺ ions from the solution will gain electrons and be reduced to solid copper, which can be represented as: \[ \text{Cu}^{2+} (aq) + 2e^- \rightarrow \text{Cu (s)} \] - Therefore, Statement 1 is **true**. 2. **Analyzing Statement 2**: - The statement claims that the standard oxidation potential (SOP) of copper is less than that of water and that the standard reduction potential (SRP) of copper is greater than that of water. - The standard oxidation potential (SOP) is the potential required for a species to be oxidized. For copper to oxidize at the anode, its SOP must be greater than that of water. Therefore, the claim that SOP of copper is less than that of water is **incorrect**. - However, the standard reduction potential (SRP) of copper is indeed greater than that of water, which means copper ions will be reduced at the cathode. - Thus, while the second part of Statement 2 is true, the first part is false. Therefore, Statement 2 is **false**. 3. **Conclusion**: - Statement 1 is true, and Statement 2 is false. Therefore, the correct answer is that Statement 1 is true and Statement 2 is false. ### Final Answer: - Statement 1: True - Statement 2: False
