4. Conclusions

Standard reduction potentials can be used to classify compounds according to their oxidizing and reducing properties. These thermodynamic data are indispensable for predicting the stability of compounds, or for calculating electrode potentials useful in a variety of practical situations, such as determining formal potentials and equilibrium potentials using the Nernst equation, or calculating equivalence potentials in redox titrations. In the thermodynamic analysis of corrosion phenomena, the equilibrium potentials of metal and oxidant are calculated using the Nernst equation. Here again, knowledge of the standard reduction potentials is essential for the calculations.

It's worth pointing out here that the use of thermodynamic data, i.e. standard potentials, only enables us to predict the possibilities, or impossibilities, of reactions among the hypotheses considered....
