acidified zinc sulphate is the electrolyte

(D) In the electrolytic refining of zinc,the anode is made of impure zinc,while a strip of pure zinc acts as the cathode. An acidified solution of zinc sulphate is used as the electrolyte. When electricity is passed,the following reactions occur:At the cathode: $Zn^{2+} + 2e^{-} \longrightarrow Zn_{(pure)}$At the anode: $Zn_{(impure)} \longrightarrow Zn^{2+} + 2e^{-}$
