Gouy, Debye-Hückel, and Fick: Understanding Differential Equations without Solving Them
Robert de Levie
Department of Chemistry, Georgetown University, Washington, DC 20057
Cover
January 1999
Vol. 76 No. 1
p. 129
Abstract
Concepts such as ionic strength, activity coefficients, ionic adsorption, and the coagulation of colloids all derive from the Poisson-Boltzmann differential equation. Mass transport involves Fick's equation. Here we illustrate a simple method to extract the most relevant information from such equations without the tedium of solving them explicitly.
