The object of the study is the oxidation–reduction reactions of nitrogen and the known values of standard electrode potentials of the corrosion processes in building materials, products, and structures. The importance of searching for consistent (consistent with the known) values, determination of missing and correction of available reference data is relevant and in demand both for specialists who study electrochemical and corrosion processes and engineers who calculate durability of buildings and structures. The available reference data on oxidation–reduction half-reactions and the known values of standard electrode potential was analyzed. The peculiarities of nitrogen half-reaction behavior in acid and alkaline media were established. As a result, three groups of components in the media were identified. The first group of components is stable in acid and alkaline media, the second group is stable in acid and the third group is stable in an alkaline medium. The components of the second and third groups can pairwise change each other under the change of the medium pH. The peculiarities of the components behavior in media have necessitated the search for the consistent values of standard electrode potential for the acid and alkaline media. The relationship between these values for pH = 0 and pH = 14 was established. The reference array was supplemented with eight oxidation–reduction half-reactions with the known values of standard electrode potential. A full search of the consistent values of standard electrode potential for acid and alkaline media was carried out and structuring with the use of potential schemes was performed. The information array of standard electrode potentials and oxidation–reduction half-reactions is not fully described in the reference literature, which complicates and hinders both the calculations and practical application of corrosion processes, and restrains the development of promising directions in various branches of chemistry and construction materials science. The developed technique of searching for consistent values was used to supplement the existing information array of standard electrode potentials and oxidation–reduction half-reactions.
