### E potentials

Will E potentials always be given as reduction potentials, even on tests? Or could it possibly be given as an oxidation potential? Some sources online use oxidation potentials instead. Is this something I should carefully pay attention to on tests?

### Re: E potentials

it will always be given as reduction as it allows for easy comparison to determine what will be oxidized and what will be reduced based the voltage value for the reduction reaction

One of the UAs said that the values that will be given to us will be reduction potentials, not oxidation potentials.

I think the reduction potentials will always be given for calculating Ecell. However, I do think that it is possible for them to give the E of oxidation and then you would have to do Ecell = Ecathode + Eanode.

I think that the only way we have been learning and the only way they do it in the textbook is in terms of reduction potentials, so that's probably what we should pay attention to
