Question

Four metals and their methods of refinement are given
$(i) \,Ni, Cu, Zr, Ga$
$(ii)$ electrolysis, van Arkel process, zone refining, Mond’s process
Choose the right method for each.

• A. Ni : Electrolysis, Cu : van Arkel process, Zr : Zone refining, Ga : Mond’s process
• B. Ni : Mond’s process, Cu : Electrolysis, Zr : van Arkel process, Ga : Zone refining
• C. Ni : Mond’s process, Cu : van Arkel process, Zr : Zone refining, Ga : Electrolysis
• D. Ni : Electrolysis, Cu : Zone refining, Zr : van Arkel process, Ga : Mond’s process

Answer 1

Answer: (B)

Nickel is purified by Mond's process. Copper is refined by using electrolytic reduction. Zirconium by Van-Arkel process, semi conductors like Ge,Si etc., are refined by Zone refining.
