Chapter 3, Problem 61A

Describe how a homogeneous mixture differs from a heterogeneous mixture.

Interpretation Introduction

Interpretation:

The difference between homogeneous and heterogeneous mixtures needs to be explained.

Concept introduction:

Mixtures are the combination of two or more pure substances. They are impure in nature. They can be separated by magnetic separation, evaporation etc.

Mixtures are of two types:

Homogeneous mixture

Heterogeneous mixture.

Explanation of Solution

The mixtures in which the components are mixed uniformly are known as homogeneous mixtures. It is also known as solution. The homogeneous mixture cannot be judge by seeing it. They have only one phase. The homogeneous mixtures cannot be separated physically.

Examples of homogeneous mixture are rainwater, vinegar etc.

The mixtures in which the components are not mixed uniformly are known as heterogeneous mixtures. The heterogeneous mixture can be judge by seeing it. They have two or more phases. The heterogeneous mixtures can be separated physically.

Example of heterogeneous mixture is mixture of sand and sodium chloride.
