Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
To solve the given problem, we need to match the metals with their respective refining processes. We have two lists:
List I: Metals
- A - Ni (Nickel)
- B - Si (Silicon)
- C - Sn (Tin)
- D - Cu (Copper)
List II: Refining Processes
- I - Zone refining
- II - Liquation
- III - Electrolysis
- V - Vapour phase refining
Explanation:
- Ni (Nickel) - Vapour phase refining (V): Nickel is often refined using the Mond process, which is a type of vapour phase refining.
- Si (Silicon) - Zone refining (I): Zone refining is typically used to purify semiconductors like silicon.
- Sn (Tin) - Liquation (II): Tin is often refined using liquation to separate it from impurities with higher melting points.
- Cu (Copper) - Electrolysis (III): Electrolytic refining is commonly used to purify copper.
Therefore, the correct matching is:
- A - V, B - I, C - II, D - III
This matches the given correct answer.
