Summary
An exact result for the electrostatic potential of a phospholipid membrane modeled by a fixed charge sheet and diffuse double layer of the Gouy-Chapman theory is given. The dependence of the potential with distance is expressed in simple form for positive divalent ions (alkaline earth cations) added to monovalent cations and anions in the bathing solution. The result has applications in the study of the effect of divalent cations on nerve or muscle excitation and on the formation of blood clots.
