Good Agreement

The concepts of ionic solvation are discussed and the definition of four types are suggested. Utilizing Webb's theory, values of the dielectric constant of water in terms of distance from a divalent ion are evaluated. The statistical mechanics of the distribution of solvent molecules round a divalent ion in aqueous solution has been worked out.The present theory shows that all divalent ions with radius less than 1.6 Å can have a saturated envelope of eight water molecules in excess of the Goldschmidt co-ordination number have to be accounted for as inner primary solvation number. The concept of catonium is suggested for such a stable aquo-complex entity. The catonium entity is further hydrated electrostatically in the normal way by primary and secondary solvation types. The conditions governing all types of solvation and their possible termination boundaries are discussed and evaluated.The theoretically calculated values of the ionic solvation numbers are in good agreement with the experimental results.

<div> <p>As natural aqueous solutions are far from being pure water, being rich in ions, the properties of solvated ions are of relevance for a wide range of systems, including biological and geochemical environments. We conducted ab initio and classical MD simulations of the alkaline earth metal ions Mg<sup>2+</sup> and Ca<sup>2+</sup> and of the alkali metal ions Li<sup>+</sup>, Na<sup>+</sup>, K<sup>+</sup> and Cs<sup>+</sup> in pure water and electrolyte solutions containing the counterions Cl<sup>–</sup> and SO<sub>4</sub><sup>2–</sup>. Through a detailed analysis of these simulations, this study reports on the effect of solution chemistry (composition and concentration of the solution) to the ion–water structural properties and interaction strength, and to the dynamics, hydrogen bond network, and low-frequency dynamics of the ionic solvation shell. Except for the ion–water radial distribution function, which is weakly dependent on the counter-ions and concentrations, we found that all other properties can be significantly influenced by the chemical characteristics of the solution. Calculation of the velocity autocorrelation function of magnesium ions, for example, shows that chlorine ions located in the second coordination shell of Mg<sup>2+</sup> weaken the Mg(H<sub>2</sub>O)<sub>6</sub><sup>2+</sup> hydration ‘cage’ of the cation. The result reported in this study suggest that ionic solvation shell can be significantly influenced by the interactions between other ions present in solution ions, especially those of opposite charge. In more general terms, the chemical characteristics of the solution, including the balance between ion-solvent and ion-ion interactions, could result in significant differences in behavior and function of the ionic solvation shell.</p> </div>
