Conversely, a species with a higher oxidation potential possesses a higher tendency to lose electrons and be oxidized (Zanello 2003). The reduction and oxidation potentials for a given species are identical in value but opposite in sign. 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.The reduction potentials in the table are, indirectly, an index of differences in electronic energy levels. The electron on gold is at a higher energy level than if it were on fluoride. It is thus motivated to spontaneously transfer to the fluorine atom, generating a potential in the circuit of 1.04V. The greater the E ∘ value means greater is the tendency shown by the species to accepts electrons and undergo reduction. So higher the (E ∘) values lesser is the tendency to undergo corrosion.
