THIRUPATHI REDDY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
    **Primary Concept**: Electrolytic refining process
    **Related Topics**: Electrochemistry, Anode and Cathode processes
    **Prerequisites**: Understanding of electrolysis and metal deposition
## SOLUTION PATHWAY
**Given Information**:
        - Impure metal is used in electrolytic refining.
        - Pure metal is deposited during the process.
**Method & Steps**:
    1. Identify the roles of the electrodes in electrolytic refining.
        Reasoning: In electrolytic refining, the impure metal is oxidized to release metal ions, which then migrate towards the cathode where they are reduced and deposited as pure metal.
        Formula/Rule: Oxidation occurs at the anode, and reduction occurs at the cathode.
    2. Determine the positions of the electrodes.
        Working: The impure metal, which is oxidized, must be at the anode. The pure metal is deposited at the cathode as it gains electrons.
        Key Point: The anode is always where oxidation takes place, while the cathode is where reduction occurs.
    3. Conclude with the identification of the electrodes.
        Result: The impure metal acts as the anode, and pure metal is deposited at the cathode.
        Verification: The roles align with the definitions of anode and cathode in an electrolytic cell.
## OPTION ANALYSIS
[A] :x: The impure metal cannot act as the cathode since it is oxidized, not reduced.
[B] ✓: The impure metal indeed acts as the anode, and pure metal is deposited at the cathode, matching the defined roles in electrolysis.
[C] :x: Both positions cannot be the anode as that contradicts the fundamental electrochemical principles.
[D] :x: The cathode cannot be the source of the impure metal, which is oxidized at the anode.
## LEARNING AIDS
    **Common Mistakes**:
        1. Confusing anode and cathode: Remember, anode is where oxidation occurs (loss of electrons), and cathode is where reduction occurs (gain of electrons).
        2. Misunderstanding the flow of ions: Clarity on how ions move towards electrodes can help avoid confusion.
    **Quick Tips**:
        1. Use the mnemonic "Red Cat, An Ox" to remember that reduction happens at the cathode and oxidation at the anode.
        2. Visualize the setup of an electrolytic cell to reinforce learning about electrode functions.
