Chapter 13, Problem 101AP

Interpretation Introduction

Interpretation:

The van’t Hoff factor of ${\text{Na}}_{\text{3}}{\text{PO}}_{\text{4}}$ is to be determined.

Concept Introduction:

The van't Hoff factor is defined as the ratio between the actual concentration of particles that are formed when the substance is dissolved and the concentration of a substance that is calculated from its mass.

Sodium phosphate dissociates in aqueous solution to form sodium cation ${\text{Na}}^{+}$ and phosphate anion, ${\text{PO}}_4{}^{3-}$.
