Key Points: Van't Hoff Factor
It is the ratio of the experimental value of colligative property to theoretical value of colligative property.
\[i=\frac{\text{Experimental value of colligative property}}{\text{Theoretical value of colligative property}}\]
\[i=\frac{(\Delta T_f)}{(\Delta T_f)_o}=\frac{(\Delta P)}{(\Delta P)_o}=\frac{\Delta T_b}{(\Delta T_b)_o}=\frac{(\pi)}{(\pi)_o}\]
