In case a solute associates in solution, the van't Hoff factor,

Colligative properties of solution depend upon the number of particles present in solution. Experimental values colligative properties for electrolytes are always higher than these obtained theoretically because electrolyte dissociates to furnish more ions in solution. The ration of experimental values to theoretical values is called as van't Hoff factor (i) . For 1M solution of a weak acid HA , the dissociation constant K in terms of van't Hoff factor:

Colligative properties of solution depend upon the number of particles present in solution. Experimental values colligative properties for electrolytes are always higher than these obtained theoretically because electrolyte dissociates to furnish more ions in solution. The ration of experimental values to theoretical values is called as van't Hoff factor (i) . van't Hoff factor for dimerisation of benzoic acid in water, assuming 70% degree of association:

A solute forms a pentamer when dissolved in a solvent. The van't Hoff factors 'I' for the solute will be :

For solutes which do not undergo any association or dissociation in a solute, van't Hoff factor (i) will be

The electrolyte solutions show abnormal colligative porperties.To account for this effect we define a quantity called the Van't Hoff factor given by i=("Actual number of particles in solution after dissociation")/("Number of formula units initially dissolved in solution") i=1 ("for non-electrolytes") igt1 ("for electrolytes, undergoing dissociation") ilt1 ("for solutes, undergoing association") Answer the following questions: Benzoic acid undergoes dimerization in bezene solution. The Van't Hoff factor i for the solutions is
