Answer 1

Explanation:

Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. ... In one technique, the anode is made of the metal to be plated on the part.

(2.) Electroplating of iron:-

For electroplating an iron object with copper metal :

1)The iron object is made negative electrode that is cathode.This means that the iron object is connected to the negative terminal of the battery.

2)A copper plate is made positive electrode that is anode. This means that a copper plate is connected to the positive terminal of the battery.

3)Copper sulphate solution is taken as electrolyte.

Conclusion: During electroplating with copper, copper metal gets transferred from positive electrode to the negative electrode.

Answer 2

1. What is Electroplating ?

Ans :- Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. ... It is also used to purify metals such as copper.

2. Explain Electroplating of iron ?

Ans :- Electroplating is the process of depositing a layer of a metal on a metallic or a nonmetallic electrode by electrolysis in an electrolytic cell. Let us take an iron spoon which is to be electroplated with copper.
