Chapter 15.3, Problem 20LC

Interpretation Introduction

Interpretation: To determine that the mixture is a suspension.

Concept Introduction: A mixture is the physical mixing of two or more substances while maintaining their own identities, and it can take the shape of solutions, suspensions, as well as colloids.

Answer to Problem 20LC

Suspension appears hazy or muddy.

Explanation of Solution

The size of the particles makes a distinction between a suspension and a solution. An aggregation of ions or molecules is called a solution (very, very small). Transparent means that you can see through a solution. Because the particle sizes in a suspension are larger, it may appear hazy or muddy.

A finely dispersed solid in a liquid would be called a "solid in suspension," and the mixture is heterogeneous. Unlike when salt, as well as water, as well as water, are combined, the solid would not be dissolved in the liquid.

A suspension is similar to a water and sand solution. The sand will spread out across the water after mixing. The sand will sink to the bottom if not disturbed.
