Chapter 14, Problem 54A

Interpretation Introduction

Interpretation:

The statement “not all mixtures are solutions” has to be explained.

Concept Introduction:

Mixture: Mixture is a combination of two or more pure components in which each pure component retains its individual chemical properties. Substances tend to mix naturally, it is difficult to keep any substance in pure form.

Types of Mixtures: Depending upon the nature of the components that form a mixture, we can have different types of mixtures and can be classified as either heterogeneous or homogeneous.

Homogeneous mixture: A homogeneous mixture is a mixture that has a uniform composition throughout; it always has a single phase. A solution is an example of homogeneous mixtures where two components form a single phase. Components cannot be distinguishable in the mixture.

Solution: The solution is a homogeneous mixture of two components. One of them is the solute and the other is the solvent. The solvent is present usually in a higher proportion than the solute in the solution. Components of the solution cannot be distinguishable in the mixture.

Explanation of Solution

The solution is a homogeneous mixture of two components and it always has a single phase. Mixtures can also be either heterogeneous or homogeneous, where heterogeneous mixture forms at least two phases that remain separate from each other and homogeneous mixture forms a single phase. So, the solution is an example of mixtures. In other words, we can say all solutions are mixtures but all mixtures are not solutions.
