In the electrolytic purification of copper some gold is found in the

Options

A. Cathode
B. Cathode mud
C. Anode mud
D. Electrolyte

Answer

To solve the question regarding the electrolytic purification of copper and the presence of gold, 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, such as copper. In this process, an impure metal is used as the anode, and pure metal is deposited at the cathode.

2. **Identifying the Anode and Cathode**:
- In the electrolytic cell, the anode is where oxidation occurs, and the cathode is where reduction takes place. For copper purification, the impure copper is placed at the anode.

3. **Impurities in Copper**:
- The impure copper contains various metals, including gold (Au), silver (Ag), nickel (Ni), and zinc (Zn). These metals are considered impurities that need to be removed.

4. **Movement of Impurities**:
- During electrolysis, when the current passes through the solution, the copper ions from the anode dissolve into the electrolyte. The impurities, including gold, do not dissolve in the same way and tend to remain at the anode.

5. **Final Outcome**:
- As a result, while the pure copper is deposited at the cathode, the impurities, including gold, are found at the anode. Therefore, the correct answer to the question is that some gold is found in the anode.

### Conclusion:
The answer to the question is that in the electrolytic purification of copper, some gold is found in the **anode**.
