2H+(aq,1 M) + 2e− ⇌ H2(g,1 atm) E∘ = 0 V 2 H + ( a q, 1 M) + 2 e − ⇌ H 2 ( g, 1 atm) E ∘ = 0 V. E ° is the standard reduction potential. on page 6; more reduced molecules are at the lower right of the chart. The more reduced a molecule is, the more potential energy it contains to be released for biological work. For example: NH 4 + NO 2 – e– releases energy O2 H2O NH4+ is reduced; it has a tendency to release e– (it is Standard Reduction Potentials (25 o C).

Reduction potential is measured in volts (V) or millivolts (mV).

Corrosion, the degradation of metals as a result of electrochemical activity, requires an anode and a cathode in order to occur. The anode is the metal or site with a higher potential to oxidize (lose electrons) while the cathode is the metal or site with a higher potential for reduction (gaining of electrons).

How to read a standard reduction potential table. Strongest reduction half-reactions are on top (largest positive EMF values) Strongest oxidation half-reactions are at the bottom (largest negative EMF values) A species will be reduced by something below it in the chart. Reduction potential (also known as redox potential, oxidation/reduction potential, or E h) measures the tendency of a chemical species to acquire electrons and thereby be reduced.

Having compared many reactions to the standard hydrogen potential, we can now make a table of reduction potentials for all half-reactions, (or oxidation potentials but we need to pick one and stick to it). Below is an abbreviated table showing several half-reactions and their associated standard potentials.
