When NaCl dissolves in water, the positive end of water surrounds the Cl- ion, and the negative end of water surrounds the Na+end of salt. Which forces are present between these ions and the water molecule?
Correct answer: B. Ion dipole forces
- A. Dipole-dipole forces
- B. Ion dipole forces
- C. H-bond
- D. Debye force
Explanation
Forces that are present between ions and water molecules are called ion-dipole forces.

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.
