- nickel, titanium
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
• Mond’s process $\longrightarrow$ refining of nickel using volatile \( Ni(CO)_4 \)
• Van Arkel method $\longrightarrow$ refining of titanium and zirconium using iodide process
Step 1: Identify metals.
Mond’s $\longrightarrow$ Nickel
Van Arkel $\longrightarrow$ Titanium (also Zr)
Step 2: Match option.
Correct pair: Nickel, Titanium
