Thermodynamics of solutions of interacting aggregates by methods similar to surface thermodynamics. Part 1.—General equations for multi-component systems

TLDR: In this paper, the Kirkwood-buff theory of solutions is applied to solutions of interacting multicomponent charged aggregates and exact expressions which account for aggregation explicitly are derived and compared with the corresponding equations for small systems in a solvent given by T L Hill.

Abstract: The general results obtained previously when methods similar to those of surface thermodynamics were used to provide an alternative derivation of part of the Kirkwood—Buff theory of solutions are applied to solutions of interacting multicomponent charged aggregates General and exact expressions which account for aggregation explicitly are derived and are compared with the corresponding equations for small systems in a solvent given by T L Hill It is shown how the theory can be used to discuss conformation changes in macromolecules A general interpretation in molecular terms of the behaviour of the micelle point in multi-component solutions is also given Finally, expressions are presented for the interpretation of light scattering data
