In the electrolytic refining of Cu

Impure metal is made as anode and pure metaforme cathode

Impure metal foms cathode and pure metal forms anode

Pure metal forms both anode and cathode

Cu motal is not used as electrodes

the impure metal us not of zinc

graphite is at the anode

the metal ion gets reduced at the anode

acidified zinc sulphate is the electrolyte

deposited at the anode

deposited at the cathode

deposited below the cathode as cathode mud

left behind in solution as copper ions
