What does solvated mean?
Solvated describes a particle that is surrounded by solvent molecules. When an ion or other solute is dispersed in a liquid, the molecules of that liquid interact with it and form an organized shell around it. The resulting solvated particle may differ substantially in shape, mobility, stability, and reactivity from the same particle in isolation. The term is used in physical chemistry, spectroscopy, electrochemistry, and related fields, especially in expressions such as “solvated ion,” “solvated species,” and “solvated electron.” Although “solvated” is closely related to “dissolved,” it places emphasis on the molecular environment surrounding a particular particle. This distinction is important because solvent interactions can change the energy, geometry, and chemical behaviour of ions and molecules. The word is consequently especially useful when discussing how substances behave within a particular medium rather than merely being present in solution.
adjectiveChemically surrounded by solvent molecules. In a solvated state, solute particles are stabilized by interactions with the molecules of the liquid or other surrounding medium in which they are dispersed.
- Surrounded by solvent molecules and stabilized by interactions with the solvent.
"The solvated ion interacts strongly with surrounding water molecules."
"Solvated electrons can act as powerful reducing agents in chemical reactions."
"The structure of the solvated ion differs from that of the same ion in a vacuum."
A solvated particle wears a molecular coat: solvent molecules surround it, altering its shape, mobility, and chemical behaviour.

Where does solvated come from?
The word belongs to a family derived from Latin solvere, “to loosen, unbind, or solve.” Latin developed solutionem as a noun meaning a loosening or dissolving, from which English gained “solution,” while “solvate” was formed as a chemical term through the associated stem. “Solvated” is the past participle and adjective of “solvate.” Other English cognates sharing the Latin root include “solve” and “solvent.”

How solvated is actually used
This is a technical chemistry term, usually used attributively in established expressions such as “solvated ion.” It normally describes a molecular or ionic species interacting with its surrounding solvent rather than the bulk substance simply being dissolved.
Easily confused with solvated
A substance is dissolved in a solution, whereas a solute particle is described as solvated when solvent molecules specifically surround and interact with it.
A solute is the substance being dissolved, while the adjective solvated describes a particle after it has become surrounded by solvent molecules.
