How will you electroplate an iron stick with copper? Explain the procedure in detail with the help of a well labelled diagram. what will happen if you use a silver anode in the experment
Answers
Answer:
Add a copper electrode, place it near the iron nail, and connect it to the switch (anode position). Add the copper sulfate solution to the bath and close the switch. Allow electroplating to take place for 2 minutes. The iron nail should now be sufficiently coated with copper.
Answer:
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. For this, we take a copper plate and an iron spoon as electrodes and copper sulphate (CuSO
4
) is taken as an electrolyte. The electrodes are connected through an external circuit as shown in figure. On passing current through the electrolyte, it is decomposed into Cu
2+
and (SO
4
)
2−
ions.
As Cu
2+
ion is positively charged, it moves towards the negative terminal i.e. iron spoon and gets deposited on it. Thus, iron spoon gets plated with copper. There is no scarcity of Cu atoms because the copper atoms go into the solution from the positive terminal i.e. copper plate. This process called electroplating continues until the iron spoon gets coated with copper.
