What is Solvation?

Solvation is the process by which solvent molecules surround and interact with solute molecules or ions when a substance dissolves. In aqueous solutions (hydration), water molecules orient their partial charges around dissolved ions, stabilising them in solution. The energy released during solvation (solvation enthalpy) partially offsets the lattice energy of ionic compounds, enabling dissolution. Solvation affects reaction rates, equilibria, and solubility.
