= Kirkwood–Buff solution theory
{wiki=Kirkwood–Buff_solution_theory}
The Kirkwood–Buff solution theory is a theoretical framework used in physical chemistry and statistical mechanics to describe the properties of solutions, especially regarding interactions between molecules in a solvent. It provides a systematic way to understand the behavior of mixtures and solutions by relating macroscopic observable properties (like concentration and thermodynamic functions) to microscopic interactions between individual particles.
