What is another name for the positive electrode in electrolysis?

1. Positive pole

2. Dispersive pole

3. Neutral pole

4. Active pole

The correct answer is: Dispersive pole

The correct term for the positive electrode in electrolysis is anode. In electrochemical terminology, the anode is where oxidation occurs, and this electrode attracts anions during the process. While "dispersive pole" might suggest an action or role related to dispersing a substance, it does not align with the traditional nomenclature used in electrolysis or electrochemistry. The positive pole, which is often a colloquial term for the anode, is the most commonly accepted term in practices concerning electrolysis. "Neutral pole" does not apply here as there is no neutral electrode in an electrolysis setup; all electrodes play distinct roles in the reaction. "Active pole" could imply a functioning electrode, but it too does not specifically refer to the positive electrode. Therefore, the most accurate terminology remains with the anode as the positive electrode.
