Functional transformation of experimental data and the chemical model of equilibrium for polynuclear systems-1. Family of auxiliary concentration functions curves with common cross-over point.
The differential relationships between concentration variables and some of the auxiliary concentration functions for systems with complex formation reactions have been obtained. Systems which give a family of concentration functions with a common cross-over point are discussed in detail. The derived equations were shown to be useful in the determination of the chemical model of equilibrium as well as for evaluating the accuracy of available data. The proposed approach was applied for the determination of composition and stability of complexes in some real systems.
