Question

Explain the process of coating a metal on another metal. draw a neat diagram related to this process. label the parts.

Answer 1

Answer:

Adding a coating of a metal on another metal is called electroplating.

This process is used to increase brightness or prevent degradation of a metal.

Explanation:

To electroplate iron products such as a spoon, a solution of silver nitrate (AgNO3) is taken in a container. The product that receives the coating is connected to the negative edge of the battery and thus is dealt as a cathode. A silver foil is used as anode. When electricity is passed in the solution, the metallic silver(Ag) atom from the anode donates an electron and goes into the solution as Ag+ ions. This Ag+ ion from the solution accepts an electron from the cathode and sticks itself to the cathode a metallic silver. Thus the coating is done.
