The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1. Meer weergeven 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 Meer weergeven Similarly, if a fraction $${\displaystyle \alpha }$$ of $${\displaystyle n}$$ moles of solute associate to form one mole of an n-mer ( Meer weergeven This quantity can be related to the osmotic coefficient g by the relation: $${\displaystyle i=ng}$$. Meer weergeven • When solute particles associate in solution, i is less than 1. For example, carboxylic acids such as acetic acid (ethanoic acid) or benzoic acid form dimers in benzene, so that the number of solute particles is half the number of acid molecules. Meer weergeven • Colligative properties • Thermodynamic activity • Raoult's law • Law of dilution Meer weergeven Web18 mrt. 2024 · Our expected value of Van’t Hoff factor was 4 but the observed value of Van’t Hoff factor that is obtained is 3.5 Note: The expected Van’t Hoff factor will always be greater than the observed Van’t Hoff factor. It occurs because some ions form solvation cells by binding.
