Look at the picture below and answer the following question. Explain how the process is carried out.

The given picture shows the process of electroplating. In this process, a thin layer of desired metal is deposited over another metal. For example, a layer of silver metal is deposited on a copper spoon. The process of electroplating silver is carried out by using a copper spoon as the cathode and a plate of silver metal is used as the anode. A solution of silver nitrate is used as the electrolyte. When current is allowed to pass for some time, silver metal gets deposited on the copper spoon.

Look at the picture below and answer the following question. How is the process shown in the picture helpful?

The given picture shows the process of electroplating. In this process, a thin layer of desired metal is deposited over another metal. For example, a layer of silver metal is deposited on a copper spoon. This process helps in the prevention of corrosion of various metals. It is also used to give a shiny finish to many metals. In some cases, it helps in improving the surface hardness of a metal.
