Reduction Potential

Postby eduardomorales5 » Fri Mar 13, 2020 5:18 pm

If the reduction potentials are both negative, do we take the largest value as the cathode, and the smallest as the anode?

The anode has the reduction potential that is more negative I believe

The cathode is the cell reduction potential that is most positive. So if they are both negative, then it would be the smallest negative number at the cathode.

the anode is more negative and the cathode is more positive.

even if both are negative the more negative would still be the anode
if the total Ecell is negative then you can assume that it is not spontaneous in the forward reaction and however may proceed spontaneously in the opposite direction
