The behaviour of membranes between electrolyte solutions : IV. Electrochemically active precipitates in membranes : the membrane potential at the barium sulphate-cellophane membrane
article
Impregnated membranes show peculiarities as to membrane potentials and permeability. The special behaviour of such membranes is examined by means of the example of a BaSO4‐cellophane membrane.
The membrane potential at the BaSO4 membrane is affected in a different way by different electrolytes in the adjacent solutions. The relation between the membrane potential and the pH of the adjacent solutions is expressed in
MP = 2.3026 RT/F · (pH1 − pHo).
Under the given conditions the membrane is impermeable to Ba2+ and SO42−. permeable to H+ and OH−.
