Question

The anode mud in the electrolyte refining of silver contains :

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

Answer 1

The correct option is D $Au$

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