What are colligative properties?
These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. This small set of properties is of central importance to many natural phenomena and technological applications, as will be described in this module.
Why is osmotic pressure a colligative property?
Because a column of liquid exerts a pressure, there is a pressure difference Π on the two sides of the system that is proportional to the height of the taller column. This pressure difference is called the osmotic pressure, which is a colligative property. Figure 11.3 Osmosis.
How does temperature affect colligative properties?
Colligative properties are also affected by temperature. Calculation of the properties only works perfectly for ideal solutions. In practice, this means the equations for colligative properties should only be applied to dilute real solutions when a nonvolatile solute is dissolved in a volatile liquid solvent.
