WebThe Debye–Hückel limiting law enables one to determine the activity coefficient of an ion in a dilute solution of known ionic strength. The equation is [1] : section 2.5.2. where. z i {\displaystyle z_ {i}} is the charge number of ion species i, q {\displaystyle q} is the elementary charge, κ {\displaystyle \kappa } The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. It is a linearized Poisson–Boltzmann model, which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean activity coefficients for ions in dilute solution. The Debye–Hückel equation provides a starting point for modern treatments of non-ideality of ele…

WebThe meaning of DEBYE-HÜCKEL THEORY is a theory in physical chemistry: the deviation of solutions of electrolytes from the laws of ideal solutions is due to electrical forces between ions. WebJan 16, 2024 · ABSTRACT. We propose a generalized Debye-Hückel (DH) theory by using a recent Poisson-Fermi model that accounts for the steric, correlation, and polarization effects of ions and water treated as nonuniform spheres with interstitial voids. The generalized DH theory reduces to the classical one when these effects are not considered.
