Hydration is a process in which_________________?
Correct answer: D. Both ions and molecules are surrounded by water molecules
- A. Molecules are surrounded by solvent molecules
- B. Ions are surrounded by solvent molecules
- C. Both ions and molecules are surrounded by solvent molecules
- D. Both ions and molecules are surrounded by water molecules
Explanation
Hydration is the solvation process in which dissolved ions or molecules become surrounded by water molecules. The likely wrong choice is ions surrounded by solvent molecules, which describes solvation in general, whereas hydration specifically involves water as the solvent.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
