In electrolytic purification, which of the following is made of impure metal?

Options

A. Anode
B. Cathhode
C. BothI(A) and(B)
D. None of these

Explanation

To solve the question regarding electrolytic purification and identify which part is made of impure metal, we can break down the process step by step:

### Step-by-Step Solution:

1. **Understanding Electrolytic Purification**:
- Electrolytic purification is a method used to purify metals. It involves the use of electrolysis to separate pure metal from its impurities.

2. **Components of Electrolytic Cell**:
- In an electrolytic cell, there are two electrodes: the anode and the cathode.
- The anode is the positive electrode, while the cathode is the negative electrode.

3. **Role of Anode and Cathode**:
- The anode is typically made of the impure metal that we want to purify. During electrolysis, the impure metal at the anode oxidizes and dissolves into the solution.
- The cathode is made of pure metal (or a conductive material) where the pure metal ions from the solution are reduced and deposited.

4. **Electrolysis Process**:
- For example, in the case of copper purification:
- The anode (impure copper) dissolves, releasing copper ions into the solution.
- The copper ions migrate towards the cathode (pure copper), where they gain electrons and deposit as pure copper.

5. **Conclusion**:
- In the process of electrolytic purification, the anode is made of impure metal, while the cathode is made of pure metal. Therefore, the correct answer to the question is that the anode is made of impure metal.

### Final Answer:
- **The anode is made of impure metal.**
