Question

In electrolytic refining of metals, the pure metal is taken as

• A. Anode
• B. Cathode
• C. Electrolyte
• D. Vessel

Answer 1

The Correct Option is B

To solve this question, we need to understand the process of electrolytic refining of metals.

1. Electrolytic Refining of Metals:
In electrolytic refining, the metal to be refined is used as the anode. The pure metal is deposited at the cathode during the electrolysis process.

2. Process Overview:
- The impure metal is placed as the anode in an electrolyte solution. - When current is passed, the metal from the anode dissolves into the electrolyte solution, and pure metal is deposited at the cathode.

3. Evaluating the Options:

• (A) Anode – Incorrect; the anode is made of impure metal, not the pure metal.
• (B) Cathode – Correct; the pure metal is deposited at the cathode.
• (C) Electrolyte – Incorrect; the electrolyte is the solution that facilitates the process, not the metal.
• (D) Vessel – Incorrect; the vessel holds the electrolyte but is not directly involved in depositing the pure metal.

Final Answer:
The correct answer is (B) Cathode.
