Electrolytic Refining means refining by electrolysis.
Many metals like copper, zinc, tin lead are refined by this method.
Process Of electrolytic Refining :
--> The apparatus consist of Electrolytic tank containing acidified copper sulphate solution as electrolyte.
--> A thick block of impure copper metal is made anode .
---> A thin strip of pure copper metal is made as cathode.
On passing electricity, Impure copper from the anode dissolves and goes into CUSO4 solution and pure copper from the copper sulphate solution deposits on the cathode .
Thus pure copper metal is produced at cathode . The soluble impurities goes into the solution whereas insoluble impurities settles down at anode as anode mud.
Chemical reaction :
At cathode : Cu²⁺ + 2e ---->Cu
At anode : Cu - 2e---->Cu²⁺
Thank you
l hope the answer help you

hey dear your ans a is here
a)In case of copper,
a thick block of impure copper is made anode and a thin block of pure metal is made cathode and copper sulphate solution is used as an electrolyte
. ... At the same time an equal amount of impure copper dissolves from anode into theelectrolyte solution
b)the two alloy prepared from copper is
Bronzes
A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon.
Nickel bronzes, e.g. nickel silver and cupronickel
hope u like it and make it brainlist
