Molecular interactions are central to numerous challenges in chemistry and the life sciences. Whether in solute–solvent dissolution, adverse ...

The solute particles cannot be separated from the mixture by the process of filtration. The solute particles do not settle down when left undisturbed, that is, a solution is stable.

Ask students: How can we set up a fair comparison to find out which solute is the most endothermic and which is most exothermic when dissolved in water? Be sure students know to use the same amount of ...

Increased molecular motion causes more solvent molecules to contact solute molecules and pull on them with more force, usually resulting in more dissolving. Since different substances are made from ...
