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.

Options

  1. ANi : Electrolysis, Cu : van-Arkel process, Zr : Zone refining, Ga : Mond's process
  2. BNi : Mond's process, Cu : Electrolysis, Zr : van-Arkel process, Ga : Zone refining
  3. CNi : Mond's process, Cu : van-Arkel process, Zr : Zone refining, Ga : Electrolysis
  4. DNi : Electrolysis, Cu : Zone refining, Zr : van-Arkel process, Ga : Mond's process

Correct answer

B. Ni : Mond's process, Cu : Electrolysis, Zr : van-Arkel process, Ga : Zone refining

Step-by-step solution

Ni - Mond's process; Cu: Electrolysis Zr: van-Arkel process; Ga: Zone refining.
