Key Concepts

Colligative Properties

Colligative properties are characteristics of solutions that depend only on the number of solute particles present, and not on the nature or chemical identity of those particles. These properties illustrate how adding a solute to a solvent alters the physical properties of the solvent, such as its boiling point, freezing point, vapor pressure, and osmotic pressure.

Solute Particle Concentration

The concept underlying colligative properties is that the magnitude of the effect on a solution's physical properties is determined by the concentration of solute particles. This means that solutions with equal amounts of solute particles will exhibit similar changes, regardless of what the particles are, as long as the solute does not associate or dissociate in the solvent.
