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:
