Anode is the positive electrode and attracts negative charges. Which option reflects this statement?

• A. Positive; attracts anions
• B. Negative; attracts cations
• C. Positive; attracts cations
• D. Negative; attracts anions

Answer: (A)

Electric attraction between charged surfaces and ions governs what happens at electrodes. The anode, when it is the positive electrode, has a positive charge, so it draws in negatively charged ions from the solution. This movement of anions toward the positive electrode happens to balance charge and enables the oxidation process at the anode. Therefore, describing the anode as positive that attracts anions fits the behavior you’d expect in electrochemical setups. If the electrode were negative, it would attract cations, not anions, which is why that combination doesn’t match the given statement.
