Question

Predict the state of the solute in the solution in the following situations :
(a)
When I' is found to be more than one.
(b)
When I is found to be less than one.

Answer 1

A) i>1
The solute is dissociated and had undergone dissociation.
B) i<1
The solute is associated and had undergone association.

Answer 2

The solute is in the dissociated form when the value of I is greater than one and the solute is present in the associated form if the value of I is greater than one.

• I is the Van't Hoff factor and it is the ratio of the number of the solute particles present in the solution to the number of solute particles added to the solution.
• If the value of I is greater than one it shows that there are more number of solute particles present than the number added which is a result of dissociation.
• If association of solute particles occurs, The number of particles present will be less than the number of particles added, making the value of I less than one.
