Question

Match the following:

• A. A-II, B-III, C-V, D-I
• B. A-II, B-III, C-I, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-I, C-II, D-III

Hint:

Remember the processes used for extraction and purification of metals such as Mond process and Zone refining.

Answer 1

The Correct Option is B

A. Leaching is used to extract \( \text{Al}_2 \text{O}_3 \) from bauxite.

B. Mond process is used for extracting Nickel (Ni).

C. Van Arkel method is used to obtain pure Zirconium (Zr).

D. Zone refining is used for the purification of Indium (In).

Thus, the correct matching is:

• A goes with II (Leaching is used to extract \( \text{Al}_2 \text{O}_3 \) from bauxite).
• B goes with III (Mond process is used for Nickel extraction).
• C goes with I (Van Arkel method is used for Zirconium).
• D goes with IV (Zone refining is used for purifying Indium).

Final Answer:
A-II, B-III, C-I, D-IV.
