Abstract: Simulations of simple solutes (charged and uncharged
spheres) in model water have been performed in order to elucidate aspects
of solvation in water at ambient and supercritical states. The variation
of solvation entropy as a function of solute charge has been used to
investigate hydrophobic and hydrophilic ordering and the structure-making
and structure-breaking effects of ions. Simulations with model solvents,
which differ from water in certain features, have been used to try to
identify the particular properties of water that are associated with
these phenomena.
