what is electroplating class 8

Electroplating is the process of plating a layer of any metal on another material by passing an electric current. It is mainly done for avoiding corrosion of metals and for decorative purposes. Electroplating is conducted in an electrolytic cell. The metal to be electroplated is connected to the cathode, and the electrolyte consists of the salt solution of the metal with which electroplating has to be done. The electrolyte ionizes to give positively charged ions (metal ions) which move towards the anode for electroplating the desired object. The object on which electroplating takes place is made the cathode (negative terminal), and the metal which is going to be plated as a layer on the object is made the anode (positive terminal) . The salt solution of the metal which is to be deposited is taken as electrolyte. The main reasons for performing electroplating are to make better appearance of the objects (e.g., shiny) and to protect the objects from corrosion. Electroplating is widely used in many industries like automobiles, airplanes, electronics, jewelry, toys, and many more.
