Solvation of the Electrolytic Components of Seawater

Original Paper


A new modification of the adiabatic compressibility method of investigating solvation in solutions is presented and applied to the analysis of the following structurally-related characteristics of hydrated complexes of seawater electrolytes (NaCl, KCl, MgCl2, CaCl2, Na2SO4, MgSO4) at different concentrations (0.1 to 5.0 mol⋅kg−1) and temperatures (278.15 to 308.15 K): solvation numbers (h) and their dependences on concentration, volumes of stoichiometric mixtures of ions without their hydration shells (V 2h ), compressibilities (β 1h ) and molar volumes of water in their solvation shells (V 1h ), their dependences on concentration and temperature, etc.
