Debyeinteraksjon
Debyeinteraksjon, also known as the Debye-Hückel theory, describes the electrostatic interactions between ions in an electrolyte solution. It was developed by Peter Debye and Erich Hückel in 1923. The theory explains why the activity coefficients of ions in dilute solutions are less than one, meaning they behave as if they are less concentrated than they actually are.
The core concept of the Debye-Hückel theory is the idea of an ionic atmosphere. Each ion in
The theory provides a mathematical framework to calculate the electrostatic potential around an ion and, consequently,
