Match List-I with List-II

Choose the correct answer from the options given below:

A-IV, B-III, C-II, D-I

The correct matching is: (3) A-IV, B-III, C-II, D-I

Here is a brief explanation of each process:

Zone refining:  This process is used to produce high-purity metals, such as silicon and germanium. In zone refining, a molten zone is passed through a rod of the impure metal. The impurities are more soluble in the molten metal than in the solid metal, so they tend to concentrate in the molten zone. As the molten zone passes through the rod, the impurities are swept along and removed from the rod.

Mond's process:  This process is used to purify nickel. In Mond's process, nickel is reacted with carbon monoxide to form nickel carbonyl. Nickel carbonyl is a volatile compound, so it can be easily separated from the impurities in the nickel ore. The nickel carbonyl is then decomposed to produce pure nickel.

Electrolytic refining:  This process is used to refine metals such as zinc, copper, silver, and gold. In electrolytic refining, the impure metal is used as the anode in an electrolytic cell. The pure metal is deposited on the cathode.

van-Arkel method:  This process is used to purify titanium. In the Van-Arkel method, titanium is reacted with iodine to form titanium tetraiodide. Titanium tetraiodide is a volatile compound, so it can be easily separated from the impurities in the titanium ore. The titanium tetraiodide is then decomposed to produce pure titanium.
