Solvation
| Formula / Notation | ΔG_solv = ΔH_solv - TΔS_solv; ion-dipole interactions |
|---|---|
| Also Known As | Hydration (in water), solute-solvent interaction, dissolution process |
What is Solvation?
The process by which solvent molecules surround and stabilize dissolved solute ions or molecules. In aqueous solutions, solvation is called hydration. The enthalpy of solvation (negative) provides the driving force for dissolving ionic compounds when it exceeds lattice energy.

The process by which solvent molecules surround and stabilize dissolved solute ions or molecules. In aqueous solutions, solvation is called hydration. The enthalpy of solvation (negative) provides the driving force for dissolving ionic compounds when it exceeds lattice energy.
Solvation is central to dissolving ionic compounds and polar molecules in polar solvents. Pharmaceutical solvation properties affect drug bioavailability and formulation. Understanding solvation guides the design of solvents for industrial extraction processes.
Solvation of reactive ions can accelerate corrosion and chemical reactions. Strong solvation in polar solvents increases the reactivity and bioavailability of dissolved toxic compounds.
