Reversing Potentials

Postby Ellen Amico 2L » Sat Feb 22, 2020 12:46 pm

How do we know when we need to reverse a reduction equation (to make it oxidation) and therefore multiply the reduction potential by -1?

After looking at both reduction potentials, you reverse the one that has a lower reduction potential. This is because the one with the higher reduction potential is more likely to be reduced than the one with the lower reduction potential. So, therefore, you reverse the one with the lower reduction potential as it will get oxidized instead.

Honestly, it would not matter. If your E is negative, you simply reverse it and the position of reactants and products.
