Practice Problem: Colligative Properties
What are colligative properties? They're properties of a solution, such as freezing point depression and boiling point elevation, which differ from the pure solvent. Let's do some calculations regarding these concepts!

Molality and Colligative Properties
Solute particles interfere with the physical processes a solution may undergo. These are known as the colligative processes of a solution. Ever wonder why we put salt on icy streets? Find out here!
