Abstract
High resolution AFM spectroscopy was used to investigate the oscillatory hydration forces at mica-electrolyte interfaces for the chloride salts of alkali cations for concentrations up to 4M. Pronounces force oscillations reflecting the layering in purified water are modified in an ion specific manner beyond an ion-dependent threshold concentration. While only a slight enhancement of the oscillatory forces is seen for the so-called kosmotropic (‘structure forming’) ions Na+ and K+, the force oscillations completely disappear for the chaotropic (‘i.e. ‘structure-breaking’) ions Cs+ and Rb+ suggesting a disruption of the hydration layers
