Definition

quantity given by:

φ = - {(M_{A} \sum b_{B})}^{- 1} ln a_{A}

where $M_{A}$ is the molar mass (molar mass) of the solvent $A$ , $\sum$ denotes summation over all the solutes, $b_{B}$ is the molality of solute $B$ (molality), and $a_{A}$ is the activity of solvent $A$ (activity of solvent)

grandeur donnée par:

φ = - {(M_{A} \sum b_{B})}^{- 1} ln a_{A}

où $M_{A}$ est la masse molaire (molar mass) du solvant $A$ , $\sum$ indique la sommation pour tous les solutés, $b_{B}$ est la molalité du soluté $B$ (molality) et $a_{B}$ est l'activité du solvant $A$ (activity of solvent)

Notes

The name "osmotic coefficient" is generally used, although the name "osmotic factor" is more systematic.

This concept especially applies to a dilute liquid solution.

Le nom «coefficient osmotique» a aussi été utilisé bien que «facteur osmotique» soit plus systématique.

Ce concept s'applique tout particulièrement à une solution liquide diluée.
