Question

The ratio of the observed value of a colligative property to the normal value of the same property is termed as ______ and is represented by ______.

Answer 1

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).
