उत्तर
The ratio of the observed value of a colligative property to the normal value of the same property is termed as van’t Hoff factor and is represented by i.
Explanation:
The van’t Hoff factor (i) accounts for the effect of association or dissociation of solute particles in solution.
It is calculated as
i = `"Observed colligative property"/"Calculated colligative property"`
For nonelectrolytes (no dissociation or association), i = 1.
For dissociation, i > 1 (more particles).
For association, i < 1 (fewer particles).
