The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression. The van 't Hoff factor is the ratio between the actual … Visa mer Similarly, if a fraction $${\displaystyle \alpha }$$ of $${\displaystyle n}$$ moles of solute associate to form one mole of an n-mer (dimer, trimer, etc.), then $${\displaystyle i=1-\left(1-{\frac {1}{n}}\right)\alpha .}$$ Visa mer • When solute particles associate in solution, i is less than 1. For example, carboxylic acids such as acetic acid (ethanoic acid) or Visa mer • Colligative properties • Thermodynamic activity • Raoult's law • Law of dilution • Van 't Hoff equation Visa mer This quantity can be related to the osmotic coefficient g by the relation: $${\displaystyle i=ng}$$.
