11.3 Colligative Properties | High School Chemistry

Chad provides a comprehensive lesson on colligative properties first explaining how these are properties of a solution that depend upon solute concentration. He explains what the van't Hoff factor is and shows how to determine its value for strong electrolytes and nonelectrolytes. He then describes the four main colligative properties and performs example calculations for each: 1) Freezing Point Depression, 2) Boiling Point Elevation, 3) Raoult's Law (Vapor Pressure Depression), and 4) Osmotic Pressure.
