>1. The electrical double layer at a Donnan membrane is capacitor-like.
capacitor-like - yes
exactly like capacitor - no
there's more to Donan system than capacitor formed by the membrane
there are charged ions swimmin' 'round on both sides.

not valid at all - it misses a large part of the system - ions.
the system has only limited similarity to capacitor.
you're trying to make your argument look like flat capacitor
filled with a nonconducting dielectric and separating
two solutions is supposed to work the same like a donnan
system. utterly wrong.
do your reading. there's a large number of reviews on the subject
(ie on the electrostatics of membrane systems).
>Obviously a special experiment is needed, and I hope one day it will
the exeriments were done. I've already gave you pointers. do your reading.
