The anode mud in the electrolytic refining of silver contains

Options

  1. AZn, Cu, Ag, Au
  2. BZn, Ag, Au
  3. CCu, Ag, Au
  4. DAu only

Correct answer

D. Au only

Step-by-step solution

The anode mud in the electrolytic refining of silver contains Au only. Metals, which are less reactive than Ag, remain in anode mud, and metals which are more reactive than Ag metal will be in electrolyte solution.
