DebyeHückelin
DebyeHückelin is a theory of ionic solutions that describes non-ideal behavior arising from electrostatic interactions between dissolved ions. Named for Peter Debye and Erich Hückel, the approach provides a framework to estimate activity coefficients of ions in dilute electrolytes and remains a foundational concept in classical electrolyte chemistry.
The theoretical framework treats ions as charged spheres embedded in a dielectric continuum and uses ideas
Historically proposed in 1923 by Debye and Hückel, the theory explains deviations from ideal behavior and informs
In practice, DebyeHückelin remains a standard starting point in physical chemistry for understanding electrolyte solutions. It
