write the terms of the following expression -9Electroplating is the process of depositing a layer of a metal on a metallic or a nonmetallic electrode by electrolysis in an electrolytic cell.

Let us take an iron spoon which is to be electroplated with copper. For this, we take a copper plate and an iron spoon as electrodes and copper sulphate (CuSO

) is taken as an electrolyte. The electrodes are connected through an external circuit as shown in figure. On passing current through the electrolyte, it is decomposed into Cu

and (SO

)

2−

ions.

As Cu

2+

ion is positively charged, it moves towards the negative terminal i.e. iron spoon and gets deposited on im physically disabled for life.
