CH110 FA10 SAS 2 By the end of Today’s Lecture you should know: Colloids Tyndall Effect Hydrophobic vs. Hydrophilic Reverse Osmosis KEY QUESTIONS: THE BIG PICTURE Colloids and Solutions in the Environment What effects does solute concentration have on the physical properties of liquids? What differences are there when the solutes do not form homogeneous mixtures? Remember: macroscopic properties come from microscopic origins What is the origin of colligative properties? How do the colligative properties of solutions impact the environment? How do colloids impact the environment?
