  "term": "Osmotic coefficient",
  "field": "Chemistry",
  "definition": "A dimensionless quantity that measures the deviation of the colligative properties of a real solution from those of an ideal solution, particularly related to osmotic pressure and vapor pressure lowering. It accounts for the non-ideal behavior of solutes due to intermolecular interactions. For an ideal solution, the osmotic coefficient is equal to one.",
