In summary, the solubility of ionic compounds is greater when there is a significant size difference between the ions and when there is a greater difference in their electronegativities. Footnotes. WebFeb 16, 2024 · Solvation is the process of reorganizing solvent and solute molecules into solvation complexes and involves bond formation, hydrogen bonding, and van der Waals forces. Solvation of a solute by water is called hydration. And, the solute ion/molecule around which this hydration shell is formed is said to be hydrated. (Image source)
WebAug 24, 2024 · The Role of Enthalpy in Solution Formation. Energy is required to overcome the intermolecular interactions in a solute, which can be supplied only by the new interactions that occur in the solution, when each solute particle is surrounded by particles of the solvent in a process called solvation (or hydration when the solvent is water). Thus … WebA sheathe of water molecules surrounding the biomolecule, whose properties vary from those of the mass due to its proximity.
