The reduction of lithium ion has a reduction potential E 0 = -3.04 V. This reaction would only occur if it were driven by an expenditure of energy. The opposite reaction, on the other hand, would be the oxidation of lithium metal to give a lithium cation. That reaction would occur spontaneously, and would have a spontaneous "oxidation potential".The more positive the cell potential, the greater the tendency of this reaction to occur and the stronger the oxidizing agent M 2 +. Through the relation E° = – Δ G° /nF it is apparent that a standard half-cell reduction potential is simply the decrease in the free energy per mole of electrons transferred to H + ions under the conditions that define the SHE.Oxidizing Agents. If one reagent in a reaction contributes oxygen, extracts hydrogen, or extracts electrons, it is said to be an oxidizing agent. Of course, it is reduced in the process. Since oxidation and reduction are symmetric processes, always occurring together, there is always an oxidizing agent and a reducing agent in the reaction.The reduction potential is a measure of the tendency of the oxidizing agent to be reduced. Its value is zero for H + + e − → 1 ⁄ 2 H 2 by definition, positive for oxidizing agents stronger than H + (e.g., +2.866 V for F 2 ) and negative for oxidizing agents that are weaker than H + (e.g., −0.763 V for Zn 2+ ).P680+ is said to be the strongest biological oxidizing agent.
