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, $Zn:$ 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)

$Ni:$ Mond's process, $Cu:$ Electrolysis, $Zn:$ van Arkel process, $Ga:$ Zone refining

$Ni$ is refined by Mond's process.

$Cu$ is refined by Electrolysis.

$Zn$ is refined by Van Arkel process.

$Ga$ is refined by Zone refining.
