Figure 3. Physicochemical system of two compartments separated by a membrane permeable only to small cations.

Figure 3.

A, Starting conditions with c1 and c2 concentrations of NaA and KA salts in their respective compartments. B, Conditions after salt dissociation and cationic redistribution (impermeant anions remained in their respective compartments). C, Concentrations obtained after x has been solved. D, Example of ionic redistribution when starting with a 10-fold gradient difference between NaA and KA.
