Which metal is refined by Mond's process?

Options

A. Titanium
B. Copper
C. Nickel
D. Zinc

Answer

C

Explanation

The Mond's process is used for the purification or Ni. It is the most important process for getting 99.9% pure Ni metal from crude Ni. In this process , the crude Ni is heated in the stream of CO to form volatile nickel carbonyl, `Ni(CO)_4`. This `Ni(CO)_(4)` when heated higher , it will decomposed to give pure metal .
`Ni+4CO overset(330-350K)to Ni(CO)_(4) overset(450-470K)to underset("(Pure)")(Ni)+4CO`
