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. $\begin{array}{cc}Ni=\text{Electrolysis}& Cu=\text{Van-Arkel process}\\ Zr=\text{Zone refining}& Ga=\text{Mond's process}\end{array}$
• B. $\begin{array}{cc}Ni=\text{Mond's process}& Cu=\text{Electrolysis}\\ Zr=\text{Van-Arkel process}& Ga=\text{Zone refining}\end{array}$
• C. $\begin{array}{cc}Ni=\text{Mond's process}& Cu=\text{Van-Arkel process}\\ Zr=\text{Zone refining}& Ga=\text{Electrolysis}\end{array}$
• D. $\begin{array}{cc}Ni=\text{Electrolysis}& Cu=\text{Zone refining}\\ Zr=\text{Van-Arkel process}& Ga=\text{Mond's process}\end{array}$

Answer 1

The correct option is B $\begin{array}{cc}Ni=\text{Mond's process}& Cu=\text{Electrolysis}\\ Zr=\text{Van-Arkel process}& Ga=\text{Zone refining}\end{array}$

$Ni=\text{Mond's process}$
$Cu=\text{Electrolysis}$
$Zr=\text{Van-Arkel process}$
$Ga=\text{Zone refining}$
