Discussion Overview

The discussion centers on adapting the Donnan Equation for systems involving three diffusible ions. Participants explore potential methods and challenges associated with this adaptation, including the applicability of alternative equations.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the adaptation of the Donnan Equation specifically for three diffusible ions.
  • Another participant suggests using the Goldman Equation as a possible alternative approach.
  • A different participant notes the lack of relative permeabilities, indicating a limitation in applying the proposed equations.
  • One participant mentions difficulties with the chloride component of the equation, suggesting a specific challenge in the adaptation process.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best approach to adapt the Donnan Equation, and multiple competing views remain regarding the methods and challenges involved.

How do you adapt the Donnan Equation to 3 difffusible ions?
 
Physics news on Phys.org
Use the Goldman Equation?
 
I don't have the relative permeabilities.
 
here is the Q, can't do the chloride part.
