Vedclass · Answer

(D) In the electrolytic refining of silver,the impure silver acts as the anode. Metals that are less reactive than silver,such as gold $(Au)$ and platinum $(Pt)$,do not dissolve in the electrolyte and settle down at the bottom of the anode as anode mud. Metals that are more reactive than silver,such as copper $(Cu)$ and zinc $(Zn)$,dissolve in the electrolyte solution. Therefore,the anode mud contains noble metals like $Au$ and $Pt$.
