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
