What is mixture in Chemistry?

A mixture refers to a combination of two or more

  • Substances
  • Materials
  • or components

among which no chemical linkage present.

Characteristics of mixture

In a mixture, the individual components retain their chemical identities and properties, and they can be separated from each other through physical means such as

  • Filtration
  • distillation,
  • or chromatography.

Mixtures can exist in various states of matter, such as

  • Gas
  • Liquid
  • or solid

and they can have different compositions and proportions of the individual components.



Examples of mixtures are given below :


Air is a mixture of different gases, primarily

  • nitrogen (about 78%)
  • and oxygen (about 21%),

along with small amounts of other gases such as

  • carbon dioxide,
  • neon
  • and helium.


Saltwater is a mixture of water and salt, with the salt called  the solute and water called the solvent.


Soil is a heterogeneous mixture of numerious components, including

  • organic matter
  • minerals
  • water
  • air
  • and living organisms.

Trail mix:

Trail mix is a heterogeneous mixture of various food items such as

  • Nuts
  • Seeds
  • dried fruits
  • and sometimes chocolate or candy.


Brass is an alloy produced from a homogeneous mixture of copper and zinc, with the quantity of each metal predicting the properties of the alloy.


Types Of Mixtures

Following are the  two main types of mixtures:

  • homogeneous
  • and heterogeneous.

Homogeneous mixture:

A homogeneous mixture is a mixture in which the components are  thoroughly distributed throughout the mixture.

Heterogeneous mixture:

A heterogeneous mixture is a mixture in which the components are not uniformly distributed.

There no visible borders or regions of different composition in homogenous mixtures. There are visible boundaries or regions of different composition.
The features of the mixture are the same throughout, and it has a smooth  look. The features of the mixture can differ in different parts of the mixture, and it has a rough appearance
 Examples of homogeneous mixtures include


Examples of heterogeneous mixtures include
 Saltwater Air and alloys such as brass.


mixture of oil and water, a salad, and a mixture of sand and gravel.
