Electroplating involves coating an object with a thin layer of pure metal via electrolysis. It's like giving your metal object a brand new, shiny outfit!
Oxidation at Anode: Metal anode is oxidized to produce cations in the solution.
Reduction at Cathode: These cations travel and get reduced at the cathode, forming a metal layer.
Impurities in the Process: Impure copper as anode? No problem!
Want pure copper? Use impure copper as the anode. As it erodes, pure copper plates onto the cathode. Impurities either chill with the old anode or swim in the solution.
