Question

We get some items made from iron wire in which iron wire is coated with plastic. Is plastic coated by the process of electroplating? Why can't plastic be coated on a metal by the process of electroplating?

Answer 1

No, plastic cannot be coated on a metal by the method of electroplating.
The reason is plastic does not dissociate into ions and does not allow passage of current as it is not a conductor. So, it does not act as an electrolyte or an electrode.
So plastic cannot be coated on a metal by the process of electroplating.
