Question

An iron is to be coated with copper. how can we do this without using electricity​

Answer 1

As Cu2+ 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.
