Salt and ions are ubiquitous in every chemical and biological reaction in aqueous environment and therefore of fundamental interest. Intriguingly, different salt types affect the stability of colloidal and biological systems, as for example molecules in aqueous solution, very differently. These ion-specific effects can be attributed to salt properties in homogeneous solution (bulk) and to the interaction of ions with interfaces. In this thesis we will address both, but limit ourselves to simple model surfaces. Molecular dynamics (MD) simulations, in which water molecules and ions are simulated explicitly in atomistic detail, are used as an input to liquid state theory in order to study both bulk and interfacial properties of aqueous electrolyte solutions.
