What is the difference of Homogeneous and Heterogeneous Mixture ?

HOMOGENEOUS MIXTURE

A mixture which is perfectly uniform in its composition and properties throughout is called homogeneous mixture. Liquid homogeneous mixture are called solutions. Kerosene is a homogeneous mixture of many hydrocarbons, solution of common salt in water, some common alloys (e.g. brass) etc are homogeneous mixtures. 

HETEROGENEOUS MIXTURE

A mixture which has different compositions and different properties at different locations in the mixture is called heterogeneous mixture. For example muddy water from a pond. Mixture containing sugar and sand are heterogeneous mixtures. Some other heterogeneous mixtures are:- 

1. A mixture consisting of sodium chloride (or common salt, and iron powder (or fillings).  

   2. A mixture consisting of common salt and sulphur. 

3. A mixture consisting of an oil and water.
