What is the meaning of heterogeneous mixture?

Answer 1

A mixture that does not have uniform composition and properties throughout.

Answer 2

Heterogeneous Mixture Explained

Suspensions and emulsions are two special types of heterogeneous mixture. A suspension is a mixture of solids and liquid in which the solids do not dissolve in the liquid solution. When a suspension is allowed to stand for some time and left undisturbed, the solid particles settle at bottom of the container. An example of suspension is sand in water and clay in water. An emulsion is a special type of suspension where a mixture consists of two liquids which do not mix together. When two such liquids are kept together they do not mix, no matter how much you try to do so by shaking or stirring. They will ultimately settle into two layers one above the other when left undisturbed for considerable period of time. Examples of emulsions are kerosene and water and a mixture of oil and water. Both suspensions and emulsions show the Tyndall effect.

The definition of a heterogeneous mixture is one which does not have a uniform composition and has visible sharp boundaries. Heterogeneous mixture are those in which the substances are not distributed evenly. They usually involve a mixture of a solid in a solid. The main difference between solutions and mixture is that a solution can only be separated into its original components by chemical means whereas a mixture can be separated by mechanical means. For example, if you mix sugar granules in a glass of water, the sugar granules completely dissolves in the water. This sugar solution is an example of homogeneous mixture. Now if you want to separate the sugar crystals from the sugar solution it is not possible to do so by mechanical means. For this you have to first boil the sugar solution so that all the water evaporates into the air and the sugar crystals will be left behind.

Now let us take the example of a mixture. If you have a heterogeneous mixture of two substances say, sand and iron fillings then you can easily separate them by mechanical means. This can be done by using a magnet to sift the iron fillings away. All you will be left behind is the sand. Thus a simple mixture can be separated by mechanical means. Some other mechanical means by which a mixture can be separated are sifting, filtration and by using gravity.

Heterogeneous Mixture Examples

Now that we have answered the question as to what is heterogeneous mixture in chemistry, let us list some examples of heterogeneous mixture.

• Sand in water
• Smoke
• Blood
• Chicken soup
• Protoplasm
• Silt in water
• Tomato Juice
• Clouds
• Vinegar in oil
• Air
• Mayonnaise
• Ice tea
• Concrete
• Wood
• Oil paint
• Hand cream
• Salad dressing
• Soil
• Chocolate chip cookie
• Muddy water
• sugar and cornstarch
• Salt and iron fillings
• Salt and Sugar mixture
• Mixture of different types of cereals
• Mixture of stones in soil
• Trail mix
• Lentil soup
• Peanut butter
• Aerosol spray

So this was all about heterogeneous mixture and how they can separated into their individual components. The most important thing to remember is that heterogeneous mixture consists of visibly different phases and substances and they are never chemically combined.

Answer 3

To make this simple lets say we put some men and women into a room you can clearly see the men and women that fill the room and distinguish them.Now we fill the room with women and no men the women are all identical sisters and look exactly the same.The men and women together are heterogeneous and the identical sister in a room are homogeneous.

Answer 4

one of two or more substances that are not mixed evenly

Answer 5

it means that you can see the different parts in it.

examples- salad, Pizza, or spagahetti.

NON examples- milk, water, Orange Juice (unless it has pulp in it)

Answer 6

A mixture of things that differ in some way.
