Many of the metals such as Cu,Au,Ag,Al,Hb etc are purified by this method.

- wherein

The impure metal is made anode while a thin sheet of pure metal acts as a cathode. 

 

 In electrolytic refining of copper, electropositive impurities like Fe, Zn, etc dissolve in the solution and less electropositive impurities like Ag, Au, etc collect below the anode.

Sn \: and\: Ag

This option is incorrect.

Option 2)

Pb \: and\: Zn

This option is incorrect.

Option 3)
