Question

The anode mud in the electrolytic refining of silver contains:

• A. Zn, Cu, Ag, Au
• B. Zn, Ag, Au
• C. Cu, Ag, Au
• D. Au only

Answer 1

The correct option is D Au only

$Au$ is less reactive than Ag. Hence, it remains in the anode mud. Metals that are more reactive than $Ag$ will be in the electrolytic solution. The anode mud in the electrolyte refining of silver contains $Au$.

Hence, the correct answer is option $\text{D}$.
