The ability of an organism to carry out oxidation-reduction reactions depends on the oxidation-reduction state of the environment, or its reduction potential (E h). Strictly aerobic microorganisms can be active only at positive E h values, whereas strict anaerobes can be active only at negative E h values.

Metals having standard reduction potential near about -2.0 volt or more negative like alkali metals, alkaline earth metals are strongly electropositive in nature. Moderately electropositive metals: Metals having values of standard reduction potentials between 0.0 and about -2.0 volt are moderately electropositive.A negative reduction potential, on the other hand, indicates a reaction that would not occur spontaneously. For example, we would not expect lithium cation to accept an electron. We are used to thinking about alkali metals easily giving up their electrons to become cations.Galvanic cells have positive cell potentials, and all the reduction reactions are reversible. The reaction at the anode will be the half-reaction with the smaller or more negative standard reduction potential.

Jun 14, 2018 · Reduction potential indicates the power to add hydrogen, lose oxygen or attract electrons. As the redox potential increases in value and turns positive, its ability to oxidize is enhanced. When it decreases in value and turns negative, its reducing ability is quantitatively enhanced. It has some resemblance to pH value of a liquid.

Oxidation–reduction potential ( Eh) is a measure of the ability of chemical/biochemical systems to oxidize (lose electrons) or reduce (gain electrons). A positive value indicates an oxidized state, whereas a negative value indicates a reduced state. The Eh of milk is about +150 mV and that of cheese is about -250 mV.
