Q4 / 116 · NTA Abhyas (NEET) 2020 · Chemistry · General Principles and Processes of Isolation of Metals

The anode mud in the electrolytic refining of silver contains

  • A
    Zn, Cu, Ag, Au
  • B
    Zn, Ag, Au
  • C
    Cu, Ag, Au
  • Correct answer
    D
    Au only

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.

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