Question

HELP!!!!
Discuss the similarities and differences between electro-refining of copper and copper plating of a bracelet? Electrolytic diagrams should be included

Answer 1

Wikipedia has a good explanation of how electroplating works:
>> http://en.wikipedia.org/wiki/Electroplating

Answer 2

Electrorefining utilizes the electrochemical dissolution of an impure copper anode in an electrolytic cell containing a copper sulfate-sulfuric acid solution. Copper ions are transported to the cathode where they are deposited with suitable purity. The basic electrochemical reactions involved are:

Anodic Reaction: Cu (impure) ® Cu2+ + 2e(Eq. 1)

Cathodic Reaction: Cu2+ + 2e ® Cu (pure)(Eq. 2)

Net Reaction:Cu (impure)® Cu (pure)(Eq. 3)
