E cell

Postby Michael Du 1E » Tue Mar 03, 2020 9:48 pm

Just for clarification, is the equation E cell = E cathode - E anode the same as simply adding the reduction potential for the cathode and the oxidization potential (the flipped number of the reduction potential) of the anode? thank you

yes, it's the same thing. I would use the method of adding the reduction potential of the cathode and flipping the other rxn and adding the flipped E naught value. It makes more sense logically and it is for sure right.

Yes, that is correct! both are good methods but the one where you flip the value for oxidation usually makes more sense conceptually.
