`i=("Actual number of particles in solution after dissociation")/("Number of formula units initially dissolved in solution")`
`i=1 ("for non-electrolytes")`
`igt1 ("for electrolytes, undergoing dissociation")`
`ilt1 ("for solutes, undergoing association")`
Answer the following questions:
For a solution of a non-electrolyte in water, the Van't Hoff factor is

The colligative properties of electrolytes require a slightly different approach than the one used for the colligative properties of non-electrolytes. The electrolytes dissociate into ions in a solution. It is the number fo solute particles that determines the colligative properties of a solution. The electrolyte solutions, therefore, show abnormal colligative properties. To account for this effect we define a quantity called the van't Hoff factor, given by : i=("Actual number of particles in solution after dissociation")/("NUmber of formula units initially dissolved in solution") i=1 (for non-electrolytes) , i gt 1 (for electrolytes, undergoing dissociation) i lt 1 (for solutes, undergoing association). The molare mass of the solute sodium hydroxide obtained from the measurement of the osmotic pressure of its aqueous solution at 27^(@)C is 25 "g mol"^(-1) . Therefore, its dissociation percentage in this solution is :

For a non-electrolytic solution, van't Hoff factor is equal to

For a solution of AlCl_(3) in water, the Van't Hoff factor (i) is greater than 1 .

For a solute undergoing association in a solvent, the van't hoff factor

In case a solute associates in solution, the van't Hoff factor,

In association of solute, the Van't Hoff factor is greater than unity.
