Question

What is the difference between dissolution and solvation?

Answer 1

Solvation is the process of attraction and association of molecules of a solvent with molecules or ions of a solute. As ions dissolve in a solvent they spread out and become surrounded by solvent molecules.

Dissolution is a kinetic process, and is quantified by its rate. Solubility quantifies the dynamic equilibrium state achieved when the rate of dissolution equals the rate of precipitation.

Or in simple terms we can define as...

Solubility is a chemical property referring to the ability of a given substance, the solute, to dissolve in a solvent. Dissolution, or solvation, is the process by which a solute interacts with and becomes dissolved in a solvent due to an increase in stability.
