Question

(a) What do you understand by the term "electroplating"?

(b) Why do we electroplate certain articles?​

Answer 1

Answer:

Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.

Articles are electroplated to make it more shiny as well as to make it rust free. It is also used in jewelery industry to electroplate the costly articles over the cheaper on like we do coating of gold over silver to make it more attractive. Electroplating is now a days common phenomenon in artificial jewelery making.

• Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating.
• ️Electroplating creates a protective barrier to reduce friction and prevent tarnishing of a surface as well as protecting surfaces from wear and tear by applying a thin, durable metal coating. ️Coating a non-metallic surface with metal changes the surface qualities of an object.
