Which metal is refined by Mond process?

  • A
    Titanium
  • B
    Copper
  • Correct answer
    C
    Nickel
  • D
    Zinc

Solution

Nickel is refined by Mond process. \(\underset{\text{pure}}{\mathrm{Ni}} +4 \mathrm{CO}\xrightarrow[]{330-350 \mathrm{~K}} \mathrm{Ni}\left(\mathrm{CO}_{4}\right)\) \(\mathrm{Ni}\left(\mathrm{CO}_{4}\right) \xrightarrow[]{450-470 \mathrm{~K}} \underset{\text{pure}}{\mathrm{Ni}}+4 \mathrm{CO}\) Reaction in Mond Process

Hence, the correct answer is option: 'C'.
