Which one of the following set of metals deposits as anode mud during the process of electrolytic refining of copper?

Options

  1. ASn and Ag
  2. BPb and Zn
  3. CAg and Au
  4. DFe and Ni

Correct answer

C. Ag and Au

Step-by-step solution

In the electrolytic refining of copper, anodic mud contains less electropositive metals like Ag, Au, Pt, Pd, etc and impurities like Fe, Zn, Ni, Sn, Pb etc. which are more electropositive metals pass into the solution.
