Conclusions
-
1.
The effect of the H2SO4 concentration and ratio of the components in a mixed aqueous-organic solvent on the real potential values of the Fec/Fec+ system was studied.
-
2.
A mathematical equation was derived that expresses the value of the real potential (Ep) as a function of the H2SO4 concentration and amount of organic solvent in an aqueous-organic medium.
