(a) The main points of difference between homogeneous and heterogeneous mixtures are given below:
Sl.No.Homogeneous Mixture Heterogeneous Mixture
1) A homogeneous mixture is a substance that is uniform in composition. A heterogeneous mixture is a mixture in which the composition is not uniform.
2)  It has a single phase. It has two or more phases.
3)  Examples of homogeneous mixture are solutions such as sugar solution, salt solution. Examples of heterogeneous mixtures are sugar, sand solution, polluted air etc.
(b) Homogeneous Mixtures: soda water, air, vinegar, alcohol and water mixture, sugar and water mixture, copper sulphate solution.
Heterogeneous mixture:  wood, petrol and water mixture, chalk and water mixture.
