Dilute Electrolyte Solutions

The precision measurement of single ion diffusion coefficients in dilute electrolyte solutions would be of considerable value. A method is described which is capable of giving the required precision. It involves a modification of the open-ended capillary method by enclosure of the capillary of diffusing radioactive material in a scintillator so that its contents can be continually monitored during the course of diffusion.

Effect Of Surface

<p>Pure aqueous electrolyte solutions display a minimum in surface tension at concentrations of ~ 2 mM. This effect has been a source of controversy since first reported by Jones and Ray in the 1930s. The Jones-Ray effect and many other surface phenomena have frequently been dismissed as an artifact and linked to the presence of surface-active impurities. Herein we systematically consider the effect of surface-active impurities by purposely adding nanomolar concentrations of surfactants to dilute electrolyte solutions. Trace amounts of surfactant are indeed found to decrease the surface tension and influence the surface chemistry. However, surfactants can be removed by repeated aspiration and stirring cycles, that eventually deplete the surfactant from solution creating a “surface chemically pure” interface. Upon following this cleaning procedure, a reduction in the surface tension of millimolar concentrations of salt is still observed. Consequently, we demonstrate the Jones-Ray effect is not caused by surface active impurities. </p>
