During extraction of metals, electrolytic refining is used to obtain pure metals. During the process, the impure metal is made the anode and a thin strip of pure metal is made the cathode. The solution of the metal salt is used as an electrolyte. On passing the current through the electrolyte, the pure metal from the anode dissolves from the electrolyte. An equivalent of pure metal from the electrolyte is deposited on the cathode.
During electrolytic refining of zinc, it gets

Options

A. deposited on cathode
B. deposited on anode
C. deposited on cathode as well as anode
D. remains in the solution

Explanation

**Step-by-Step Solution:**

1. **Understanding Electrolytic Refining:**
- In electrolytic refining, we aim to obtain pure metals from their impure forms. This process involves using an anode made of impure metal and a cathode made of pure metal.

2. **Setting Up the Electrolytic Cell:**
- The impure metal (in this case, zinc) is placed at the anode, while a thin strip of pure zinc is placed at the cathode. The electrolyte is a solution containing zinc salts, typically zinc sulfate (ZnSO4).

3. **Passing Current Through the Electrolyte:**
- When an electric current is passed through the electrolyte, the anode (impure zinc) undergoes oxidation. This means that zinc atoms from the anode lose electrons and dissolve into the electrolyte as Zn²⁺ ions.

4. **Movement of Ions:**
- The Zn²⁺ ions in the electrolyte are positively charged. Since the cathode is negatively charged, these Zn²⁺ ions are attracted to the cathode.

5. **Deposition of Pure Zinc:**
- As the Zn²⁺ ions reach the cathode, they gain electrons (reduction) and are deposited as pure zinc metal on the cathode. This process continues until the desired purity of zinc is achieved.

6. **Conclusion:**
- Thus, during the electrolytic refining of zinc, pure zinc gets deposited on the cathode.

**Final Answer:**
During the electrolytic refining of zinc, it gets deposited on the cathode.
