'''Solvations''' describes the interaction of a [[solvent]] with [[Solution (chemistry)|dissolved]] molecules. Both [[ion]]ized and uncharged [[molecule]]s interact strongly with a solvent, and the strength and nature of this interaction influence many properties of the solute, including solubility,<ref>{{Cite journal |last=Suarez |first=Adiran Garaizar |last2=Göller |first2=Andreas H. |last3=Beck |first3=Michael E. |last4=Gheta |first4=Sadra Kashef Ol |last5=Meier |first5=Katharina |date=2024-10-29 |title=Comparative assessment of physics-based in silico methods to calculate relative solubilities |url=https://link.springer.com/article/10.1007/s10822-024-00576-y |journal=Journal of Computer-Aided Molecular Design |language=en |volume=38 |issue=1 |pages=36 |doi=10.1007/s10822-024-00576-y |issn=1573-4951}}</ref> reactivity, and color, as well as influencing the properties of the solvent such as its viscosity and density.<ref name=article-1 /> If the attractive forces between the solvent and solute particles are greater than the attractive forces holding the solute particles together, the solvent particles pull the solute particles apart and surround them. The surrounded solute particles then move away from the solid solute and out into the solution. Ions are surrounded by a [[Solvation shell|concentric shell of solvent]].  Solvation is the process of reorganizing solvent and solute molecules into solvation complexes and involves bond formation, [[hydrogen bonding]], and [[van der Waals force]]s. Solvation of a solute by water is called hydration.<ref>{{Cite book|title=Chemistry - California Edition|last=Cambell|first=Neil|publisher=Pearson Prentice Hall|year=2006|isbn=978-0-13-201304-8|location=Boston, Massachusetts|pages=734}}</ref>

Solubility of [[solid]] compounds depends on a competition between [[lattice energy]] and solvation, including entropy effects related to changes in the solvent structure.<ref>{{Greenwood&Earnshaw2nd|page= 823}}</ref>
