The Van Der Waals equation, for non-ideal gases, takes into consideration these intermolecular forces. Moreover, when we consider water, it is one of those substances that can occur in all three states - Solid, Liquid, and Gaseous state. MgSO4 can dissolve in water and an exothermic reaction occurs and heat is released. chemical. The number of interactions is closely related to the surface contact area of the molecules, so a large nonpolar molecule may experience quite a large amount of attraction from LDF, while a small, compact one may experience very little. This means that the forces of attraction between H2O molecules The strength of the intermolecular forces between solutes and solvents determines the solubility of a given solute in a given solvent. H2O-H2O=Hydrogen bond.
