Read the following passage and answer the questions.
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
- a)deposited on cathode.
- b)deposited on anode.
- c)deposited on cathode as well as anode.
- d)remains in the solution.
Correct answer is option 'A'. Can you explain this answer?

Answer:
Electrolytic Refining of Metals:
During the extraction of metals, electrolytic refining is used to obtain pure metals. This process involves using an electrolyte and passing an electric current through it to separate impure metals from pure metals.
The Process of Electrolytic Refining:
1. Anode and Cathode: In the process of electrolytic refining, the impure metal is made the anode (positive electrode), and a thin strip of pure metal is made the cathode (negative electrode).
2. Electrolyte Solution: The solution of the metal salt is used as the electrolyte. This electrolyte facilitates the movement of ions during the electrolysis process.
3. Passing Current: When the electric current is passed through the electrolyte, the metal ions from the impure metal at the anode dissolve into the electrolyte as positive ions. These positive ions then migrate towards the cathode.
4. Deposition on Cathode: As the metal ions reach the cathode, they gain electrons and are reduced to their elemental form. This results in the deposition of pure metal on the cathode.
5. Equivalent Metal Deposition: The amount of pure metal deposited on the cathode is equivalent to the amount of impure metal dissolved at the anode. This ensures that the impurities are removed from the electrolyte, leaving behind pure metal on the cathode.
Electrolytic Refining of Zinc:
In the case of electrolytic refining of zinc, the impure zinc metal is made the anode, and a thin strip of pure zinc metal is made the cathode. The electrolyte used is a solution of zinc sulfate (ZnSO4).
When the electric current is passed through the electrolyte, the zinc ions from the impure zinc at the anode dissolve into the electrolyte as positive ions (Zn2+). These zinc ions migrate towards the cathode, where they gain electrons and are reduced to their elemental form.
Therefore, during the electrolytic refining of zinc, the pure zinc metal gets deposited on the cathode. This deposition of pure zinc ensures the removal of impurities from the electrolyte and the production of high-quality zinc metal.
Hence, the correct answer is option 'A' - the pure zinc metal gets deposited on the cathode during the electrolytic refining of zinc.
