reduction and oxidation

Postby Savannah Mance 4G » Wed Mar 04, 2020 10:46 pm

Is the element that is being reduced the one with a standard reduction that is the smallest or the most negative? and the one that is oxidized the one with the biggest or most positive standard reduction?

The species that is reduced is the one with the more positive standard reduction potential. The species that is oxidized is the one with the more negative standard reduction potential. This set-up will result in a positive cell potential.

Whichever species has the higher positive standard reduction potential will act as the oxidizing agent and be reduced.

It's the other way around. Since Ecell = Ecathode-Eanode, you want the Eanode to be the most negative so that the overall cell potential is positive. At the anode, oxidation occurs.
