Balancing Redox Reactions

Postby melissa_dis4K » Tue Feb 26, 2019 5:07 pm

In class why did Professor Lavelle change the Cu^2+ + 2 e- ---> Cu reaction to the reverse reaction?

Cu was probably the reducing agent, meaning that the reaction occurred in the anode (since the other reaction must've had a larger Ecell value). This would mean that oxidation occurs in the anode, making the reaction the reverse reaction.

He reversed it because copper was being oxidized in the reaction.

The reaction was reversed because it was Cu that was being oxidized during the reaction, meaning that it occurred in the anode.
