Electroplating is based on:
(a) heating effect of electricity
(b) chemical effect of electricity
(c) physical effect of electricity
(d) magnetic effect of electricity

The correct answer will be option (b) chemical effect of electricity.

Electroplating is based on the chemical effect of electricity.

Explanation

Chemical effect of electric current-  When an electric current passes through a conducting solution, it causes chemical reactions, as a result, bubbles of gas are formed, or deposits of metal are seen on electrodes or changes in the colour of the solution, may occur.

Electroplating- It is the process of depositing a thin layer of any desired metal on another material by means of electricity. It is useful for coating a cheaper metal with a more expensive one (such as copper or silver), to prevent corrosion, make objects appear shiny and resistant to scratches.
