Chad provides a comprehensive lesson on Colligative Properties. The lesson begins with the definition of the van't Hoff Factor and a straightforward presentation on how to determine its value for strong electrolytes and nonelectrolytes from a chemical formula. Next, calculations involving Freezing Point Depression and Boiling Point Elevation are demonstrated along with how to determine relative freezing and boiling points for different solutions. Next, Raoult's Law for Vapor Pressure Depression is covered and a sample calculation is performed. Finally, the lesson concludes with a sample calculation of Osmotic Pressure.

I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at https://www.chadsprep.com/chads-gener...
