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

When solute associates in a solution, the value of Vant Hoff factor is,

When an electrolyte is dissociated in solution, the van.t Hoffs factor (i) is ,

In case of electrolyte which dissociates in the solution the van Hoff factor I

For a solute undergoing association in a solvent, the van't hoff factor

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

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

Acetic acid undergoes dịmerisation in benzene solution, the van't Hoff factor i is related to the degree of association of the acid as
