Question

Describe the process of electroplating of copper metal on an iron nail

Answer 1

we take electrolyte (cuso4) and anode and cathode,,here anode is copper and cathode is iron.on passing electric current the electrolyte dissociates into cu+ and so4- ions.cu goes and accumulated on iron(cathode).lower concentration of cu ions make the anode (copper) ions to get in electrolyte.thus whole of the copper gets plated on iron.copper gets reduced as it is plated on iron.electroplating zinc on iron is called galvanization.
mark it as brainiest plz..
