colligative properties
{{march 10th, 2023{{
colligative properties:
- it should make sense that when you dissolve something to form a solution, the solution shouldn’t have the same properties as the original substances
- colligative properties are properties that depend on the relative concentration of the solute in a solution, as well as the nature of the solute
more particles dissolved = bigger effect
boiling point elevation:
- liquid particles easily shift into the gas phase at the normal boiling point, there are NO OBSTACLES for the liquid particles
- the solute particles prevent the liquid particles from escaping & turning into gas, this requires the liquids to possess more energy to become a gas
freezing point depression:
- however, this solid cannot shift into the liquid phase at the normal freezing point temperature because the solute particles BLOCK MOVEMENT from the solid to liquid phase
- solid particles can easily shift into the liquid phase at the freezing point, there are NO OBSTACLES for the solid particles
