Vedclass · Answer

(D) In the electrolytic refining of metals like zinc,an impure metal rod is used as the anode and a pure metal strip is used as the cathode.An electrolyte solution containing a salt of the metal (e.g.,zinc sulfate) is used.When an electric current is passed through the electrolyte,the metal from the impure anode dissolves into the solution as metal ions $(Zn^{2+})$.These metal ions then migrate towards the cathode,where they gain electrons and get reduced to form pure metal,which deposits on the cathode.Therefore,during the electrolytic refining of zinc,pure zinc is deposited on the cathode.
