Question

how electroplating is done and uses of electroplating

Answer 1

Electroplating is known as electrodeposition because the process involves depositing a thin layer of metal onto the surface of a work piece, which is referred to as the substrate. An electric current is used to cause the desired reaction
The plating metal, or coating, (gold) is connected to the anode (positively charged electrode) of the electrical circuit, while the jewelry piece is placed at the cathode (negatively charged electrode). Both are immersed in a specially developed electrolytic solution (bath).

Answer 2

salt of metal is chosen which is to be coated over another metal .metal which is to be coated is dipped in the solution and connected with the negative pole. Metal for Desired coating is connected with positive pole
when electric current is passed to the solution metal from anode is dissolved in the salt solution and deposit it over the negative pole the coating of desired metal is obtained on another metal
wheel rims, handle of cycle, taps are made Shiny by the method of electroplating
