Derivations of Vinograd and McBain (1941) were applied to explain ionic diffusion out of sea water and into dilute solution. Models so constructed were found to be compatible with experimental data obtained from Cl-, K+, Mg2+ and Ca2+ diffusion studies. The present investigation suggests that ionic interaction-resulting from the electroneutrality requirement-may extensively modify fluxes of diffusing ions and may also affect the relative distribution of both migrating and non-migrating ions. It is suggested that a change in the ratio ion Cl in interstitial waters of marine sediments does not necessarily imply that the ion is involved in a chemical reaction or that it migrates.
