Chapter 13, Problem 55QP

Interpretation Introduction

Interpretation:

The definition of van’t Hoff factor and the information it provides are to be discussed.

Concept introduction:

The property that depends on the concentration of solute molecules and not on the identity of solute is termed as colligative property.

Van’t Hoff factor is a colligative property.

The fraction of mole of reactant that underwent dissociation is termed as the degree of dissociation or van’t Hoff factor.

$i\text{=}\frac{\text{actual}\text{number}\text{of}\text{particles}\text{in}\text{solution}\text{after}\text{dissociation}}{\text{formula}\text{units}\text{initially}\text{dissolved}\text{in}\text{solutions}}$
