This is the process of electroplating .
DEFINITION OF ELECTROPLATIN
electroplating is a process where A coating of metal is added to a conductor using electricity via a reduction reaction... when a current is applied to the conductor to be coated , metal ions in solution are reduced onto the electrode to form a thin layer.

Hi friend,
The process of depositing a layer of metal on the surface of other objects using electric current.
=>Procedure and observation-:
Arrange the set up as shown in the pic.
On passing electric current the expensive shine metal at anode dissolves and enter the electrolyte.
The electrolyte dissociates into copper and sulphate the metal from the anode, combine with sulphate and maintain the concentration by forming copper sulphate again.
Simultaneously, the broken copper from the solution move towards cathode and settles on it.
Towards thee end of reaction anode dissolves and cathode thickens (polished).
REACTIONS-:
At anode--->oxidation
Cu---->2e^- + Cu^+2
Copper metal oxidises to copper cation.
At cathode---> reduction
Cu+2 + 2-e ---> Cu
Cation reduces to copper metal.
USES OF ELECTROPLATING-:
It is used for making decorative items and polished utensils and used for refining and redressing of metals.
Hope it helps..............
