I'm not sure if this is the correct forum to post this type of question, but here goes. Let's say I have two volumes divided by a proton conducting membrane (Nafion). Each side contains a different concentration of H2SO4 (aq) solution, so they will dissociate into protons, sulfate, and bisulfate ions. Will the concentrations of each of the ions eventually be equal on both sides? If so, what exactly is happening and what are the mechanisms involved?
With my very basic understanding of diffusion and migration, I think all of the ions should travel across because of the concentration gradient. How does the proton-selectivity of the membrane affect the diffusion of the negative ions? I think the reason all of the ions have to pass through and not just the protons is that this will create a charge imbalance across the membrane. Anyway, enough rambling. Somebody please enlighten me.
