Abstract
The density and the velocity of ultrasound in aqueous solutions of rubidium chloride were measured over a broad range of concentrations and temperatures with the goal of quantitative description of structural features of hydration complexes formed by RbCl in water. The volume compression of the solvent, the hydration numbers, the molar volume, the adiabatic compressibility of water in the hydration shells of ions, and the intrinsic volume of a stoichiometric mixture of Rb+ and Cl– ions were estimated. The change in the hydration number was found to make the major contribution to the variation of the volumetric properties of hydration complexes with an increase in the electrolyte concentration, while the effect of temperature is exerted via the solvent structure.
