This process is called electroplating.
It is an example of electroplating-
We will need copper sulphate and two copper plates.Take distilled water in a clean and dry beaker. Dissolve two teaspoonfuls of copper sulphate in it. Add a few drops of dilute sulphuric acid to copper sulphate solution to make it more conducting. Clean copper plates with sand paper. Now rinse them with water and dry them. Connect the copper plates to the terminals of a battery and immerse them in copper sulphate solution.Allow the current to pass for about 15 minutes. Now remove the electrodes from the solution and look at them carefully. You will find difference in any one of them. You will find a coating over it. Note down the terminal of the battery with which this electrode is connected.When electric current is passed through the copper sulphate solution, copper sulphate dissociates into copper and sulphate. The free copper gets drawn to the electrode connected to the negative terminal of the battery and gets deposited on it.From the other electrode, a copper plate, an equal amount of copper gets dissolved in the solution. Thus, the loss of copper from the solution is restored and the process keeps going. This means that copper gets transferred from one electrode to the other.
The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.
Hope it helps you.
