Which of the following transition metals...

Which of the following transition metals is purified by the Mond process?

A

`Ni`

B

`Cr`

C

`V`

D

`CO`

Text Solution

Verified by Experts

The correct Answer is:
A
`Ni + 4CO overset(50^(@)C)rarr Ni(CO)_(4)`
Nickel carbonyl is volatile. When heated, it decomposes to form pure nickel:
`Ni(CO)_(4) overset(230^(@)C)rarr Ni + 4CO`
Thus, nickel carbonyl is used for the purification of nickel by Mond's process.
