Name the anode,the cathode and the electrolyte used in the electrolytic refining of impure copper.

Explanation

### Step-by-Step Solution

1. **Identify the Anode**: In the electrolytic refining of impure copper, the anode is made of impure copper. This is where oxidation occurs during the electrolysis process.

2. **Identify the Cathode**: The cathode used in this process is pure copper. At the cathode, reduction takes place, where copper ions gain electrons and get deposited as pure copper.

3. **Identify the Electrolyte**: The electrolyte used in the electrolytic refining of copper is a solution of copper sulfate (CuSO₄) or copper nitrate (Cu(NO₃)₂). This solution contains copper ions that facilitate the transfer of copper from the anode to the cathode.
