This 33-slide PowerPoint presentation introduces students to the concept of freezing point depression and boiling point elevation. It also includes a worksheet in which students can take notes and practice the skills learned during the lesson. • First, students will review what happens when a liquid freezes and when it boils. • Then, a discussion about how adding a nonvolatile solute would affect the freezing and boiling process. • Molality will be introduced followed by practice problems. • The freezing point depression and boiling point elevation formulas will be introduced with examples for students to work out. • Finally, a practical investigation to work out the molar mass of an unknown solute by using freezing point depression will be outlined with an example calculation. I hope you find this useful.
