What is the best way to eat a bag of jelly beans? Many people open the bag and eat all the candy, no matter what flavor each piece is. Others pick through the collection. They may say, "I don't like the orange ones." Or maybe they only care for the lemon ones. There are different kinds of jelly beans in the mixture and people will eat what they want and get rid of the rest. A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. Vegetable soup is a heterogeneous mixture. Any given spoonful of soup will contain varying amounts of the different vegetables and other components of the soup. A phase is any part of a sample
that has a uniform composition and properties. By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. In the case of vegetable soup, one phase would be the liquid soup itself. This phase has vitamins, minerals, and other components dissolved in the
water. This phase would be homogeneous. The carrots, peas, corn, or other vegetables represent other phases of the soup.The various vegetables are not mixed evenly in the soup, but are spread around at random. There are a large number of heterogeneous mixtures around us. Soil is composed of a variety of substances, and is often of different composition depending on the sample taken. One shovelful may come up with dirt and grass, while the next shovelful could contain an earthworm. Smog
is another example of a heterogeneous mixture. This murky collection of pollutants can be a mixture of water and contaminants from burning gasoline or plastics, mixed with nitric oxide derivatives and ozone. You can see that the smog distribution in the air illustrated below is not evenly spread out, but varies from one part of the atmosphere to another. Summary

glass (clear versus stained) – clear glass usually looks homogeneous, stained glass could beeither, but some stained glass has bubbles in the glass so would be heterogeneous 4.Classify the following as a pure substance or a mixture.

Homogeneous Mixture DefinitionA homogeneous mixture is a mixture of substances blended so thoroughly that you cannot see individual substances. Every sample of the mixture will show the same amounts of each substance. Homogeneous mixtures can be solid, liquid, gas, or plasma mixtures.  Properties Of Homogeneous MixturesHomogeneous mixtures have several identifying properties:
Saltwater is an example of a homogeneous mixture that can be easily separated by evaporation. Many countries use evaporation to capture pure drinking water from seawater, leaving behind salt that can be sold for profit. Sugar water is another example of a homogeneous mixture that can be separated by evaporation. Homogeneous CompoundA mixture is not a compound. In chemistry, pure substances can be chemically bonded to form compounds. If the substances do not chemically bond, they form mixtures. An example of a homogeneous compound is pure water (H2O). The hydrogen is bonded to the oxygen. Carbon dioxide is another example of a homogeneous compound. However, the air you are breathing is a homogeneous mixture. Every breath is an equal mix of nitrogen, oxygen, argon, carbon dioxide, water vapor, and some other substances. Good thing, too, otherwise you might pass out. Homogeneous Vs. Heterogeneous MixtureIn chemistry, we can have two types of mixtures: homogeneous mixtures and heterogeneous mixtures:
Before really digging into these mixtures, let's learn to say them correctly. These are five- and six-syllable words:
Both words are adjectives, not nouns. You have to use them to describe something else, like a mixture. You can't say, "This is a heterogeneous." The prefix "homos" means "same," while the prefix "hetero" means "different." The root of "geneous" is a Greek word, "genos," meaning a group, type, or stock. So, homogeneous means all the same group, and heterogeneous means all different groups together. Think of two different bowls of soup: tomato soup is homogeneous, while the vegetable soup is heterogeneous. Here are three more examples of heterogeneous mixtures:
Homogeneous Mixtures ExamplesIf you carefully look around your own home, you can see many examples of homogeneous mixtures in your house. Here is a list of household homogeneous mixtures:
Those might have seemed obvious. Consider these, too:
These are all mixtures that are uniform throughout when viewed with the naked eye. Never taste, touch, or smell chemicals at home or in a science laboratory. You can look at some items and see immediately that they are homogeneous mixtures. Everything is blended, and you cannot pick out any one item in the mixture. Homogeneous Mixtures QuizTest your knowledge of homogeneous mixtures by answering these questions:
Don't get mixed up! Do the work first, then check your answers below.
Is glass homogeneous or heterogeneous?Glass is a homogeneous mixture of super-cooled molten sodium silicate and calcium silicate.
Are glass windows heterogeneous?Glass is a homogeneous mixture. A heterogeneous mixture is one that is not chemically or physically consistent throughout the material. A homogeneous mixture is one that is chemically and physically consistent throughout the material.
Is clear glass homogeneous?Glass is a very homogeneous material among many solid materials and has isotropic properties due to its random structure. In addition, being an inorganic material, it has high durability, which makes it different from other transparent materials.
Why is glass a heterogeneous mixture?A glass of iced tea is a heterogeneous mixture as it contains both solid and liquid phases simultaneously.
