Colligative properties of a solution depends upon

Colligative properties of the solution depend upon :

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) . The correct order of freezing point for the following, each are 1 molal solutions in water and take alpha = 1 : (i) Urea , (ii) NaCl (iii) Na_(3)PO_(4) , (iv) Na_(2)SO_(4)

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:
