11.4 Colligative Properties - Chemistry 2e OpenStax

WebOsmotic pressure is a ‘colligative’ property, like freezing point depression, which means that it depends on the number of particles in solution but not on their chemical identity. The osmotic pressure (π) of an ‘ideal’ dilute solution is described by van’t Hoff's law, namely π = RTC, where R is the gas constant, T the absolute ... WebAccording to the general definition, those properties of a solution that depend on the number of solute molecules, irrespective of their nature, with respect to the total number of molecules present in the solution are called colligative properties.
