The discussion focuses on the electroplating process involving a zinc cathode and an inert anode in a copper ion solution. When current is applied, copper ions undergo reduction at the cathode, while oxidation occurs at the anode, typically involving water electrolysis. The reactions are separate but must balance each other, with the potential of the cell determined by the specific electrochemical conditions present. The conversation emphasizes the importance of understanding both half-reactions in electrochemical cells.
PREREQUISITESChemistry students, electrochemists, and professionals involved in electroplating processes will benefit from this discussion.
Ok, but the electrolysis of water is a reaction that balances itself, if there is already reduction of metal on the cathode, there can be only another oxidation which balances that reduction, is that not correct? If so, what is the exact reaction and what cathions are left in the water?Borek said:Hint: if there is nothing else to react and potential is high enough, there is always solvent present.
