Chapter 14, Problem 59A

Interpretation Introduction

Interpretation:

The type of heterogeneous mixture and the characteristic helps in classifying the mixture needs to be explained.

Concept introduction:

Heterogeneous mixture: A heterogeneous mixture is a mixture consists of a various composition in which the individual components remain separate in the mixture. The mixture forms at least two phases that remain separate from each other. Two types of heterogeneous mixtures are colloids and suspensions.

Suspension: A suspension is a heterogeneous mixture. Some of the solute particles in the suspension settle out of the mixture upon standing. The particle size in a suspension are much larger than those of a solution, so they easily settle out from the dispersion medium.

Answer to Problem 59A

The solution shown in the above figure is a suspension. The most useful characteristic is the settling time i.e, the solute particles in a suspension easily settle out while standing.

Explanation of Solution

A suspension is a heterogeneous mixture. Some of the solute particles in the suspension settle out of the mixture upon standing. The particle size in a suspension is much larger than those of a solution, so they easily settle out from the dispersion medium.
