The process of osmosis can be reversed if a pressure
higher than the osmotic pressure is applied to the solution Colligative properties
have been used to determine the molar mass of solutes Solutes which dissociate in
solution exhibit molar mass lower than the actual molar mass and those which
associate show higher molar mass than their actual values Quantitatively, the extent to which a solute is dissociated or associated can be
expressed by van’t Hoff factor i
