The Colligative Properties explain what happens to a pure solvent as it transitions to a solution.

The 4 Colligative Properties

Concept #1: The 4 Colligative Properties

Some Colligative Properties will increase and others will decrease with the addition of solute to a pure solvent.

Example #1: Pure benzene, C6H6, has a boiling point of 80.1ºC. What is a possible new boiling point once an unknown amount of glucose is added to the benzene solvent?

Concept #2: Van't Hoff Factor

Example #2: Which of the following compounds will have the largest value for the Van’t Hoff factor?

Concept #3: Solute Amount

Example #3: What is the ionic molality of potassium ions in 1.18 m solution of K3PO4?

Practice: Which of the following compounds will have the highest boiling point?

Practice: Which of the following compound will have the highest vapor pressure?
