Practice Problem: Colligative Properties

The video tutorial explains colligative properties, focusing on boiling point elevation and freezing point depression. It provides step-by-step calculations for determining the boiling point of a benzene solution and the freezing point of an NaCl solution. Key concepts such as molality, dissociation of ions, and the effects of solutes on boiling and freezing points are covered.
