1. Homogeneous Mixture

2. A homogeneous mixture is a mixture that has only one phase. Its components have a uniform composition and cannot be viewed separately in the mixture. That is why it exhibits uniformity in appearance and properties throughout the mixture. The prefix homo - comes from the Greek word homos , which means “the same”. It indicates that the two substances combined together blended well to form one uniform mixture, in which individual particles cannot be distinguished.

3. Characteristics of Homogeneous Mixtures 1. Homogeneous mixtures consist of one phase. Matter may exist in different phase. These phases include solid, liquid and gas. A homogeneous mixture only has a single phase. It can be of any of the following combinations: liguid -liquid(e.g., water and alcohol), solid-solid (e.g., copper and tin), and gas-gas (e.g., oxygen and nitrogen).

4. 2. The composition of homogeneous mixtures is identical. Since there is uniformity in the distribution of particles in a homogeneous mixture, each of its portion has the same composition and properties.

5. 3. Homogeneous mixtures look uniform in the naked eye. The first time that you look at homogeneous mixtures, you might not able to distinguish their components since they do not present any gap.

6. 4. Homogeneous mixtures cannot be filtered. In order to separates mixtures, different physical or mechanical processes may be used. However, if the mixture is homogeneous,, the filtrate, or the liquid from which a substance has been removed using a filter, will not achieve purification.

7. 5. Most homogeneous mixtures are transparent. All homogeneous mixtures are transparent except those which are homogeneous solid mixtures.

8. Different Kinds of Homogeneous Mixtures Homogeneous mixtures can be solids, liquids, or gas. Solids Solid homogeneous mixtures is present in alloys. An alloy, is a mixture of elements that have characteristics of a metal. One example of an alloy is steel which is made from a mixture of iron and carbon. All of the different elements that make up steel are spread evenly all through it.

9. 2. Liquids A liquid homogeneous mixture is called a solution . A solution is a mixture of two or more things that are mixed up together evenly. In a solution, the substance that dissolves another substance is known as the solvent . On the other hand, the substance that is dissolved is called the solute . In mixture, the solvent is usually present in greater amount than the solute.

10. 3. Gases Gases can be homogeneous mixtures too. The air that you breathe is a homogeneous mixture. It is made up of nitrogen, oxygen, carbon dioxide, and many other gases, but you cannot tell the difference between them when you are breathing since they are all mixed up and spread out evenly in the air.

11. Beneficial Uses of Homogeneous Mixtures Homogeneous mixtures play an important role in your daily life. They exist in many forms and products that you get to use everyday. The air that you breathe is considered a homogeneous mixture. It consists of different gases in certain amounts. Each layer of air is a homogeneous mixture on its own since layer of the Earth’s atmosphere has a different density.

12. The water that you drink and use is also an example of a homogeneous mixture. The dissolved minerals and gases that it contains are often dissolved throughout the water. Even though tap water and rain water may have different levels of dissolved minerals and gases, they are both considered homogeneous. The mouthwash that you use to rinse your mouth with is another example of a homogeneous mixture. It kills the bacterial plaque in your mouth that causes cavities, gingivitis, and bad breath.

13. 4. The blood plasma in your body is also an example of a homogeneous mixture. It can be described as a colorless fluid holding the blood cells in suspension . It accounts for a little more than half of the volume of a human body. 5. The perfume or cologne that you use to smell good .

14. 6. The laundry detergent that you and your family use at home. It is a homogeneous mixture of various soaps and chemicals that keep clothes clean . 7. Also the vinegar . It is a man-made mixture that often used in cooking and also used as cleaning agent . 8. The beverages that you drink (hot chocolates, juices, and milk).
