Would I2 be more soluble in CCl4 or H2O? True Ionic bonds are also generally stronger than the forces discussed below, which is why most pure salts are solids except at extremely high temperatures. All the kinds of interaction mentioned are derivatives of electrostatic interaction, also know as Coulomb interaction. 13.5: The Structure and Properties of Water, status page at https://status.libretexts.org, Dipole- Dipole occurs between polar molecules, Ion- Dipole occurs between an ion and polar molecules. Explain your answer. The strength of the intermolecular forces between solutes and solvents determines the solubility of a given solute in a given solvent. Answer (1 of 4): There will be an attraction between the charged ions and the water molecules. Ion-dipole forces always require a. an ion and a water molecule. Figure \(\PageIndex{2}\) Water (clear liquid) and oil (yellow) do not form liquid solutions. For example, one molecule of H2O is attracted to another H2O molecule because H2O is a polar molecule. KCl is a polar ionic compound. (Kb for water = 0.512 oC It is tetrahedral in shape and has resonance between all the Mn to O bonds. For example, air is a gaseous solution of about 80% nitrogen and about 20% oxygen, with some other gases present in much smaller amounts. In order to form a solution, the solute must be surrounded, or solvated, by the solvent. On an individual basis, LDF are generally the weakest of the intermolecular forces.
