Answer 2

Electroplating:

Electroplating is one of the chemical effects of electric current. Electroplating is a chemical process using which a metal is coated with a layer of another desired metal. Electroplating is done to make the metals shiny. Electroplating is done over the articles made of iron to make the iron shiny and to prevent iron from getting rusted.

Refining of impure metals:

The most widely used method for refining impure metals is electrolytic refining. Put the impure metal is made the anode and a pure metal is made the cathode in to the solution. On passing the current through the electrolyte the pure metal from the anode dissolves in to the electrolyte.
