WebMar 11, 2024 · The reason for this becomes clear when we look at the standard reduction potentials (E°) and calculate the oxidation-reduction potential (ORP). The sum of the half reaction potentials, 0.76 and 0.34 V, gives an ORP of 1.10 V in standard conditions. Because 1.10 V is positive, this indicates that the reaction is favorable and occurs spontaneously. WebThe use of redox po- tentials to predict soil corrosivity is presented in Table 4.
