Question

you are electroplating copper on an iron object which terminal of the battery is connected to the iron object ? and also mention the electrolyte you will use for it.

Answer 1

Answer:

In the process of electroplating, the metal to be electroplated is taken as cathode and the one used for coating is chosen as the anode. And, we know, the anode is the positive terminal and the cathode is the negative terminal. Thus, the negative terminal will be connected to the iron object.
