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 component is made of impure metal, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Electrolytic Purification**:
- Electrolytic purification (or refining) is a process used to purify metals extracted from their ores. Ores often contain impurities, and this method helps in separating the pure metal from these impurities.

2. **Identify the Components**:
- In the electrolytic refining setup, there are two main components: the anode and the cathode.
- The anode is the positively charged electrode, while the cathode is the negatively charged electrode.

3. **Role of the Anode**:
- The anode is where the impure metal is placed. When electricity is passed through the solution, the impure metal at the anode dissolves into the electrolyte solution.

4. **Role of the Cathode**:
- The cathode is where the pure metal is deposited. As the impure metal dissolves, pure metal ions migrate to the cathode and get deposited there.

5. **Impurities Behavior**:
- The impurities in the impure metal can be of two types:
- More reactive impurities dissolve in the solution.
- Less reactive impurities settle down as anode mud at the bottom of the electrolytic cell.

6. **Conclusion**:
- Based on this understanding, the component that is made of impure metal is the **anode**. Therefore, the answer to the question is that the anode is made of impure metal.

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