Associated solutes are the joining of two or more particles to form one entity. While dissociated solutes refer to the splitting of a molecule into multiple ionic entities.An example of association is the dimerization of carboxylic acids when dissolved in benzene. An example of disassociated solutes is the dissociation of sodium chloride (NaCl) into Na+ and Cl– ions when dissolved in water.In associated solutes, the observed molar mass is greater than the predicted value. In disassociated solutes, the observed value of molar mass is lesser than the normal value.The value of the Van’t Hoff factor is less than 1, in associated solutes. The value of i is greater than 1, in disassociated solutes.In associated solutes, the colligative properties’ values are lower than what is expected. Example: A reduced freezing point or boiling point. In disassociated solutes, higher values of colligative properties are observed. Example: Higher osmotic pressure.
