Chapter 12, Problem 46RQ

Interpretation Introduction

Interpretation:

The hypothesis that, the addition of a neutral salt to a colloidal precipitate, such as ${\text{BaSO}}_4\left(\text{s}\right)$ allows the crystal to grow in size, is to be developed.

Concept Information: van't Hoff factor is defined as the ratio between the actual concentration of particles formed when the substance is dissolved and the concentration of a constituent as interpreted from its mass.

For most of the non-electrolytes that are dissolved in water, the van't Hoff factor is $1$.
