Question

Four metals and their methods of refinement are given :

(i) $Ni,Cu,Zr,Ga$

(ii) Electrolysis, van Arkel process, Zone refining, Monds process

Choose the right method for each metal.

• A. $Ni:$ Electrolysis, $Cu:$ van Arkel process, $Zr:$ Zone refining $Ga:$ Monds process
• B. $Ni:$ Monds process, $Cu:$ Electrolysis, $Zr:$ van Arkel process, $Ga:$ Zone refining
• C. $Ni:$ Monds process, $Cu:$ van Arkel process, $Zr:$ Zone refining, $Ga:$ Electrolysis
• D. $Ni$ : Electrolysis, $Cu:$ Zone refining, $Zr:$ van Arkel process, $Ga:$ Monds process

Answer 1

The correct option is B $Ni:$ Monds process, $Cu:$ Electrolysis, $Zr:$ van Arkel process, $Ga:$ Zone refining

$Ni$ is refined by Monds process.
$Cu$ is refined by Electrolysis.
$Zr$ is refined by van Arkel process.

$Ga$ is refined by Zone refining.
