Question

What is vant hoff factor? what type of value can it have if in forming the solution, the solute molecules undergo dissociation and associated?

Answer 1

Answer:

I hope this answer satisfied sorry for bad handwriting.

Answer 2

To study the colligative properties of solutions the  Van’t Hoff factor is taken into account.

It is generally represented by the symbol ‘i’.

Hence, the  Van’t Hoff factor can be explained as:

• It is the ratio of the concentration of particles formed when a solute molecule is dissolved to the concentration of the solution by mass.

The Van’t Hoff factor for the non-electrolytic solutes is one (1).

• If the solutes molecule undergoes dissociation then the Van’t Hoff factor is greater than one.

i>1 (For dissociation)

• If the solutes molecule undergoes association then the Van’t Hoff factor is less than one.

i<1 (For association )
