Homogeneous and Heterogeneous Mixtures


A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample.

In chemistry, a mixture is a material system made up of two or more different substances which are mixed but are not combined chemically.

Conversely, a heterogeneous mixture has components whose proportions vary throughout the sample.

Homogeneity and heterogeneity are concepts often used in the sciences and statistics relating to the uniformity in a substance or organism.

Homogeneous and Heterogeneous Mixtures - Iken Edu by Iken Edu


"Homogeneous" and "heterogeneous" are not absolute terms but depend on context and the size of the sample.


In chemistry, a homogeneous suspension of material means that when dividing the volume in half, the same amount of material is suspended in both halves of the substance; however, it might be possible to see the particles under the microscope.

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains.

Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.

A microscope is an instrument used to see objects that are too small to be seen by the naked eye.


An example of a homogeneous mixture is air.

The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.


In physical chemistry and materials science that refers to substances and mixtures which are in a single phase.

Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of the principles, practices and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, dynamics and equilibrium.

The interdisciplinary field of materials science, also commonly termed materials science and engineering is the design and discovery of new materials, particularly solids.


This is in contrast to a substance that is heterogeneous.
