strong interactions are essential, solute particles will sneak in between water molecules when it is energetically favourable.

aaronq · Answer

the other points can be refuted. b) no reactions are occurring (assuming that the solute doesn't ionize), c) no bonds are broken (we'll technically yes, hydrogen bonds between water molecules will be broken but replaced with bonds with the incoming solute particles (these are intermolecular forces, not covalent bonds btw.) Covalent bonds wont be broken in this process). d) solute does not need to melt. Even if the solute is a solid, when there is a strong association between the water molecules and the solute, the water molecules will separate the large solid into smaller particles. Also, even if the solute is liquid, you still need to have strong interactions between the water and the solute particles.
