Vedclass · Answer

(B) In the process of electrolytic refining, an impure metal rod is used as the anode and a thin strip of pure metal is used as the cathode. When an electric current is passed through the electrolyte, the pure metal from the anode dissolves into the electrolyte, and an equivalent amount of pure metal from the electrolyte deposits on the cathode. The insoluble impurities present in the impure metal, which do not dissolve in the electrolyte, settle down at the bottom of the electrolytic cell below the anode. This collection of insoluble impurities is known as $Anode 	ext{ } mud$.
