Frequently Asked Questions for PHREEQC and PhreeqcI
Weblog K(conditional) = log K(thermodynmaic) * gamma(reactants)/gamma(products) where gamma(reactants) is a product of activity coefficients calculated from the ionic strength of the solution for the reactant side of the balanced reaction, each activtiy coefficient raised to the power denoted by the stoichiometric coefficient.
WebIn both models, the surface charge can be neutralized by an electrical double layer (EDL) on the surface. The composition of the EDL can be calculated by explicit integration of the Poisson-Boltzmann equation (Borkovec and Westall, 1983), or by averaging for a Donnan volume (Appelo and Wersin, 2007).
