Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct.
Electroplating is the process of depositing a layer of a metal on a metallic or non-metallic electrode by electrolysis in an electrolytic cell.
Let us take an iron spoon which is to be electroplated with copper.
For this, we take copper plate and iron spoon as electrodes and copper sulphate (CuSO
4
) is taken as an electrolyte. The electrodes are connected through an external circuit as shown in the figure.
On passing current through the electrolyte, it is decomposed into Cu
+2
and (SO
4
)
2−
ions. As Cu
+2
ion is positively charged, it moves towards the negative terminal, i.e. iron spoon, and is deposited on it. Thus, iron spoon is plated with copper. There is no scarcity of Cu atoms because the copper atoms go into the solution from the positive terminal, i.e. copper plate. This process called electroplating continues until the iron spoon is coated with copper.
