is 40 % ionised in aqueous solution.
The value of its van't Hoff factor (i) is :
Vant Hoff factor (i) -
In case of electrolytes the observed colligative property is different from theoritical colligative property. There ratio is defined by Vant Haff factor
Vant Hoff factor for dissociation -
is the no. of dissociated particles
degree of dissociation
Vant Hoff factor for Association -
number of particles associated
degree of association
e.g. Carboxylic acid dimerized in non polar solvents like Hexane.
n = 2 for dimerization
n = 3 for trimerization
