Chapter 16, Problem 124A

Interpretation Introduction

Interpretation: The nature of a substance formed by the mixing of water and soap in which it is a suspension, colloid, or solution is to be determined.

Concept introduction: Colloids are a heterogeneous mixture that contains two phases, dispersed phase, and dispersed medium.

Answer to Problem 124A

The shaking of soap and water results in the formation of a colloidal solution.

Explanation of Solution

The colloidal solution contains two phases, dispersed phase, and dispersed medium. The medium where the colloidal particles are found to be dispersed is the dispersion medium. And the colloidal particles are called the dispersion phase. The shaking of water and soap results in the formation of a colloidal solution in which water is the dispersion medium and gas is the dispersed phase.

So, soap and water are shaken together to produce a colloidal solution.
