State the differencw between hetrogeneous and homogeneous mixture. Give two examples of each for your answer.
Answers
Answer:
Homogeneous mixtures Heterogeneous mixtures
1. In Homogeneous mixtures the composition is uniform throughout the mixture. In heterogeneous mixture composition may vary from point to point.
2. We can not see the components of homogeneous mixture with naked eyes. We can see easily the components of heterogeneous mixtures.
3. Particle size of the mixture is often at atomic or molecular size. Heterogeneous mixtures possess larger particle size.
4. Components of homogeneous mixtures cannot be separated easily. Components of heterogeneous mixture can be separated easily.Mostly these are pure substances. These are not pure substances.
6. Homogeneous mixtures have uniform composition hence many times these mixtures are referred to as solutions. These mixtures consist of visibly different phases. The three phases are solid gas liquids. Sometimes these are referred to as colloids.
7. The whole mixture used to be in the same phase. Substance can be of two phases and layers may separate.
8. Examples of heterogeneous mixtures are milk, sugar solution in water, oil, gasoline etc. Examples of heterogeneous mixtures are mud and water, sand, salt and pepper mixture, air etc.
