Solvation vs. Hydration — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on September 28, 2023
Solvation is the process of molecules dissolving in a solvent, while hydration specifically refers to solvation when water is the solvent.

Key Differences
Solvation is a general term that describes the process of molecules (solute) being surrounded and dispersed evenly in a solvent to form a solution. It involves the interaction between solute particles and solvent molecules, typically driven by forces like electrostatic interactions, dipole-dipole interactions, and van der Waals forces. Hydration, on the other hand, is a specific type of solvation that occurs when water is the solvent. Water is a highly polar molecule with a unique ability to form hydrogen bonds. When a solute dissolves in water, it undergoes hydration, and the water molecules surround and interact with the solute particles.

Solvation
Solvation involves interactions between solute and solvent molecules.
In solvation, water molecules surround and interact with the solute.
Hydration
A solid compound containing water molecules combined in a definite ratio as an integral part of the crystal. Often used in combination
Pentahydrate.
Solvation
Solvation (or dissolution) describes the interaction of solvent with dissolved molecules. Both ionized and uncharged molecules interact strongly with solvent, and the strength and nature of this interaction influence many properties of the solute, including solubility, reactivity, and color, as well as influencing the properties of the solvent such as the viscosity and density.
Hydration
To rehydrate.
Solvation
Any of a class of chemical reactions in which solute and solvent molecules combine with relatively weak covalent bonds; the process of forming a solution or dispersion.
Hydration
To supply water to (a person, for example) in order to restore or maintain fluid balance
"Cold water is the fastest and safest way to hydrate an ordinary athlete" (Jane E. Brody).
Solvation
(chemistry) An association, or a reaction, of a solute with a solvent
Hydration
To become a hydrate.
Solvation
A chemical process in which solvent molecules and molecules or ions of the solute combine to form a compound
Hydration
(chemistry) The incorporation of water molecules into a complex with those of another compound.
Hydration
(biology) The process of providing an adequate amount of water to body tissues.
Hydration
(construction) The chemical reaction by which a substance (such as cement) combines with water, giving off heat to form a crystalline structure in its setting and hardening.
Hydration
The act of becoming, or state of being, a hydrate.
Hydration
The process of combining with water; usually reversible
Hydration
Hydration specifically refers to solvation when water is the solvent.
The hydration of ions in aqueous solutions is a common phenomenon.
