Quick Summary

Solvation is a process where solvent molecules surround and interact with solute molecules or ions. This interaction is crucial for dissolving substances and forming solutions. The nature of the solvent and solute dictates solubility, with similar chemical properties often leading to better dissolution. For instance, water readily dissolves methyl alcohol but not mercury.12

Solvation can involve various intermolecular forces, including hydrogen bonding, where molecules link together. This process can significantly affect the behavior of solutions and is fundamental to many chemical and industrial separation processes like absorption and extraction. When a solvent acts as a reagent in a chemical reaction, it's termed solvolysis, with specific names like hydrolysis used when water is the solvent.123

Finally, the specific solvation (or close association with the solvent) of particular ions (excluding the solvation of the proton to give SH₂⁺, which is already included in the basicity of the solvent) may be important. It is usually not easy to separate these three effects and, in particular,…

Hydrogen bonding: solvation
In a mixture of methanol and, say, pyridine (C₅H₅N), hydrogen bonds can also form between the electropositive hydrogen atom in methanol and the electronegative nitrogen atom in pyridine. Hydrogen bonding between dissimilar molecules is an example of a type of interaction known as solvation.…

…bonds, the process is called solvation. For example, in the system acetone-chloroform, a hydrogen bond is formed between the hydrogen atom in chloroform and the oxygen atom in acetone. In this case, hydrogen bonding depresses the escaping tendencies of both components, producing negative deviations from Raoult’s law.
