P725: Properties of Water: An inquiry/SWH laboratory activity

John Gelder (Oklahoma State University, USA)

An inquiry activity where students discover the effect of the addition of a nonvolatile solute on the freezing point of water will be shared along with student results. The same activity also allows students to discover how the number of solute particles affect the freezing point. Additionally an alternate approach to explain freezing point depression and boiling point elevation without phase diagrams will be presented.
