Is Matter around us Pure : Mixture


Mixtures – A Fusion of Substances                                                                                                                      


In chemistry, when two or more substances interact with each other, it results in the formation of a Mixture. The result formed due to the combination of substances does not lose its individuality nor are they combined chemically. There are two types of mixtures:

  • Homogeneous: Sugar mixed in water is the most common example of a homogeneous mixture. Homogeneous mixtures can be defined as the mixtures which possess the same properties and combination throughout their mass.
  • Heterogeneous: A mixture of sand mixed with salt is an example of a heterogeneous mixture. Heterogeneous mixtures possess different properties and compositions in various parts that are the properties are not uniform throughout the mixture.


Characteristics of Mixtures:

  • There is no chemical force acting between the two or more substances that are mixed, but they still exist together.
  • They can either be heterogeneous or homogeneous in nature.
  • The proportions of the substances vary in an indefinite manner.
  • The properties of the mixture depend upon the individual components.
  • The constituents of the mixture can be separated by physical methods.
  • Boiling point and melting point of the mixture depends upon the characteristic of the constituents.
  • During the formation of mixture, there is no change in the energy.
  • All the states of matter (solid, liquid, gases) can combine to form mixtures.

It can be concluded that almost everything in our vicinity is nothing but a mixture. For example: the food we eat is a mixture of ingredients, the atmospheric air we breathe is a combination of gases and the fuel we use in locomotives is a heterogeneous mixture.
