Abstract
A method is proposed for determining the hydration number of an individual ion within the approach (V. P. Korolev, J. Struct. Chem., 55, No. 3, 463 (2014)). In an infinitely dilute solution, the hydration numbers of ions are given by the formulas NH +4 , Cl–(H2O)2, Cl−(H2O)4, and NO -3 (H2O)7. The structure of aqueous complexes is discussed, and a structurally relevant parameter, i.e., the density of water of hydration, is determined. Salt concentration dependences are derived for the hydration number and apparent volume of NH +4 , Cl−, and NO -3 ions. The density of the cationic (Н2О-NH +4 ) and anionic (Н2О–Cl− and Н2О-NO -3 ) systems is calculated.
