Physical chemistry

Solvent molecules wrap around a dissolved particle

Solvation is the process by which solvent molecules surround and interact with a dissolved solute particle, arranging themselves into a shell that stabilises the particle and makes dissolution favourable; when the solvent is water the process is called hydration. The energy released as this shell forms (the solvation energy) is what lets an ionic solid overcome its lattice energy and dissolve. Born's 1920 Volumen und Hydratationswärme der Ionen gave the classic electrostatic estimate of an ion's solvation energy from its charge, radius, and the solvent's dielectric constant. The referent is the enveloping of a solute by solvent and the energy that accompanies it.[1]

Unit
The solvation (or hydration) energy, and the size and structure of the solvation shell
Recovery means
Not applicable
Measured by
Estimated from enthalpies of solution, the Born electrostatic model, and spectroscopic or scattering probes of the solvation shell
