Answer:
Electroplating is a chemical process using which a metal is coated with a layer of another desired metal.
EXAMPLES:
(i)Electroplating is done over the articles made of iron to make the iron shiny and to prevent iron from getting rusted.
(ii)Water pipes, which are made of iron, are coated with a layer of zinc metal by the process of electroplating. Zinc is less reactive than iron and thus prevents the iron pipe from getting rusted.
(iii)Ornaments made of silver or other cheap metals are electroplated with gold to give them appearance like gold.
(iv)Rims of wheel of cycle, cars, etc. are electroplated with chromium metal. Layer of chromium metal give them shiny appearance and prevents from rust.
(v)Tin cans used for storing food are made of iron electroplating with a coat of tin. Tin is less reactive than iron, and prevent foods packed in them from getting spoiled.
