Chapter 2.3, Problem 3RQ

Interpretation Introduction

Interpretation: The difference between a heterogenous mixture and a homogeneous mixture needs to be explained with examples.

Concept Introduction:Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.A mixture consists of two or more than two different elements or compounds.

Answer to Problem 3RQ

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. For example- mixture of sand and water, iron filing and sand etc.

A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily. For example − mixture of salt and water, water and alcohol etc.

Explanation of Solution

The homogeneous and heterogeneous mixture is the combination of components. The difference between a heterogenous mixture and a homogeneousmixture is mentioned below:

Homogeneous mixture	Heterogeneous mixture
A uniform combination of the substance is known as the homogeneous mixture.	A non-uniform combination of the two different types of components is known as heterogeneous mixture.
The entire region of the mixture is the same.	There more than one phase is present in this mixture.
They cannot be separated by the physical method.	They can be easily separated by physical method.
For example − mixture of salt and water, water and alcohol etc.	For example- mixture of sand and water, iron filing and sand etc.
