The hydration reaction is defined as the transfer of an ion or neutral chemical species from the gaseous phase into water, Mn+(g) → Mn+(aq). In this process, water molecules bind to metal ions through ion-dipole bonds of mainly electrostatic character. The hydration reaction is always strongly exothermic with increasing heat of hydration with increasing charge density of the ion. The structures of the hydrated metal ions in aqueous solution display a variety of configurations depending on the…

Quantum-chemical simulations of the hydration of Pb(II) ion: structure, hydration energies, and pKa1 value

Thermodynamic and structural aspects of the hydration of Pb(II) ions were explored based on DFT calculations combined with the supermolecular/continuum solvent model and showed that because P b(H2O)n2+ complexes with six to nine water molecules have comparable thermodynamic stabilities, such complexes are likely to coexist in aqueous solutions.

Solvation of Au+ versus Au0 in aqueous solution: electronic structure governs solvation shell patterns.

Quite surprisingly, it is discovered that the first solvation shell of Au(0)(aq) consists of a single water molecule and features both "anionic" and "cationic" solvation patterns depending on fluctuation and polarization effects.
