Ion binding to a lipid membrane is studied by application of a rapid solution exchange on a solid supported membrane. The resulting charge displacement is analyzed in terms of the affinity of the applied ions to the lipid surface. We find that chaotropic anions and kosmotropic cations are attracted to the membrane independent of the membrane composition. In particular, the same behavior is found for lipid headgroups bearing no charge, like monoolein. This general trend is modulated by electrostatic interaction of the ions with the lipid headgroup charge. These results cannot be explained with the current models of specific ion interactions.
