Colligative Properties
Learning Time: 4-12 hours
Content: Colligative properties are properties of a solution that depend on the amount of non-colloidal solute. This area covers freezing point depression, boiling point elevation, vapor pressure depression, osmotic pressure, and the van’t Hoff factor. The TYT focuses on basic colligative effects, while the AYT focuses on complex solutions and applications. In the current 2025 curriculum, it is also covered in the context of biochemistry and environmental chemistry. Learning this topic provides an important foundation for understanding solution behavior.
- Basic Colligative Properties:
- Freezing Point Depression (ΔT_f = K_f.m)
