Which of the following is a homogeneous mixture

The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their composition.

A homogeneous mixture is a mixture in which the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout. There is only one phase of matter observed in a homogeneous mixture at a time. So, you wouldn't observe both a liquid and a gas or a liquid and a solid in a homogeneous mixture. There are several examples of homogeneous mixtures encountered in everyday life:. You can't pick out components of a homogeneous mixture or use simple mechanical means to separate them.

You can't see individual chemicals or ingredients in this type of mixture. Only one phase of matter is present in a homogeneous mixture. A heterogeneous mixture is a mixture in which the components of the mixture are not uniform or have localized regions with different properties. Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter e.

Heterogeneous mixtures are more common than homogeneous mixtures. Examples include:.

Usually, it's possible to physically separate components of a heterogeneous mixture. For example, you can centrifuge spin out solid blood cells to separate them from the plasma of blood. You can remove ice cubes from soda. You can separate candies according to color. Mostly, the difference between the two types of mixtures is a matter of scale.

If you look closely at sand from a beach, you can see the different components, including shells, coral, sand, and organic matter. It's a heterogeneous mixture. If, however, you view a large volume of sand from a distance, it's impossible to discern the different types of particles. The mixture is homogeneous. This can seem confusing! To identify the nature of a mixture, consider its sample size. If you can see more than one phase of matter or different regions in the sample, it is heterogeneous.

If the composition of the mixture appears uniform no matter where you sample it, the mixture is homogeneous. Share Flipboard Email. Anne Marie Helmenstine, Ph.When you combine two or more materials, you form a mixture.

In chemistry, a mixture is a combination that does not produce a chemical reaction. There are two categories of mixtures: homogeneous mixtures and heterogeneous mixtures. Here's a closer look at these types of mixtures and examples of mixtures.

The Difference Between Heterogeneous and Homogeneous Mixtures

Homogeneous mixtures appear uniform to the eye. They consist of a single phase, be it liquid, gas, or solid, no matter where you sample them or how closely you examine them. The chemical composition is the same for any sample of the mixture.

Heterogeneous mixtures are not uniform. If you take two samples from different parts of the mixture, they will not have an identical composition. You can use a mechanical method to separate components of a heterogeneous mixture e.

Sometimes these mixtures are obvious, where you can see different types of materials in a sample. For example, if you have a salad, you can see different sizes and shapes and types of vegetables. In other cases, you need to look more closely to recognize this mixture. Any mixture that contains more than one phase of matter is a heterogeneous mixture. This can be tricky because a change of conditions can alter a mixture. For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture.

Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture. Technically, if a chemical reaction is occurring when you mix two materials, it's not a mixture Share Flipboard Email.Milk is a mixture. It is homogeneous if it has been homogenized -- otherwise it will separate and be heterogeneous.

Milk is the only mixture. Pure gold, distilled water, and helium are not mixtures. They are all made of the same molecule or atom. Milk is a mixture because it is made of water, lactose, milkfat, etc. Milk is homologous because its looks uniform throughout. If you added some oil to the milk and could see bits of oil separated in the milk, then that would be heterogeneous.

Mark Lv 7. Well, PURE anything is automatically homogeneous.I think that, instead, you are referring to phases. By phase, I mean how many different parts that make up the solution, solid or gas that you can see.

With trail mix, you physically mix say, 10 different ingredients. After mixing them, you can still see all 10 so there are 10 phases in your trail mix. Definately not homogeneous.

There are 3 types, each of which have different properties depending on what ingredient is added and these are nickel, carbon, and manganese. Stainless steal is homogeneous in that you only see one phase steel and none of the different parts from which it is made. Water is also a homogeneous mixture.

Examples of Homogeneous Mixture

Although made of hydrogen and oxygen, they form something completely different water and there is only one phase.

If you have a cup of water and take out 1 tablespoon, the contents of the tablespoon will be exactly the same homo as in the rest of the container. If I had to pick one it would be a toss up between steel and water. Of the things you have listed there, one is a compound, one is an element, one is a heterogeneous mixture you can even pick out the different componentsand one is a solution of metals in each other. A solution is a very good example of - come to think of it, is probably just the same thing as - a homogeneous mixture.

In the above question homogenous mixture is stainless steel. Becoz different metals combines to form stainless steel but all the metals are in solid state. ANS A is correct as homogeneous is a substance that you can see through and required only 1 kind of atom and the exception is milk. In this case, tomato soup can not be seen through as it is thick.

I did this exact question in my intro chemistry course today and it marked water as wrong and said that stainless steel was the correct choice!

We've covered heterogeneous mixtures in depth right herebut what about homogeneous mixtures? A homogeneous mixture is simply any mixture that is uniform in composition throughout. As long as each substance is mixed in enough to be indistinguishable from the others, it is a homogeneous mixture. One of the most interesting facts about heterogeneous and homogeneous mixtures is that, in a sense, there's no real distinction. Look closely enough at any substance, even a pure element, and it becomes heterogeneous because it's made up of different subatomic particles.

Conversely, at a large enough scale everything in the universe is homogeneous, because it becomes impossible to differentiate components. The properties of homogeneous mixtures are best defined on a scale somewhere between the two. Scientists and we most often use the simple standard of the naked eye. If a substance can be seen to contain two or more distinct components, it is considered heterogeneous.

If it appears to be just one uniform substance, it's homogeneous. There is a wide variety of solid homogeneous mixtures, from naturally occurring materials like stone to synthetic plastics. Bitumen, the solid form of petroleum and source of gasoline, diesel and other fossil fuels, is a homogeneous mixture of complex hydrocarbon chemicals. Cement is a solid homogeneous mixture of calcium compounds. Mixed with sand, gravel and water, it becomes concreteone of the most important building materials in the world.

Many alloys are homogeneous mixtures of metals, or of a metal and a nonmetallic substance. Bronze, which is made from copper and tin, is an example of the first kind of alloy. Steel, made from iron and carbon, is an example of the second. Plastics are some of the world's most important homogeneous mixtures. The discovery that certain mixtures of synthetic organic compounds could be made into solid objects changed the entire manufacturing industry.

Wood is a homogeneous mixture. The components that make up living wood are solid, liquid and gaseous, but all are metabolized by the tree into solid wood. Many of the liquids you encounter every day - indeed, most of the liquids that power your body - are examples of homogeneous mixtures. In the human body, blood plasma is an example of a homogeneous mixture. The colorless fluid holds blood cells in suspension. It makes up a little more than half of the volume of human blood.

Milk is a homogeneous colloid.

which of the following is a homogeneous mixture

Colloids are mixtures that consist of tiny, insoluble droplets floating in a solvent. Some sources say that colloids are by definition heterogeneous, but by the naked eye test, milk is a homogeneous liquid suspension of fats in water. Most wines and liquors are homogeneous mixtures. Water itself is an example of a homogeneous mixture.

All but the purest water contains dissolved minerals and gases. These are dissolved throughout the water, so the mixture presents in the same phase and is homogeneous.

Liquid laundry detergent is another example of a homogeneous mixture of various soaps and chemicals for washing clothes.

Kinds of Mixture: Homogeneous and Heterogeneous Mixture

Many of the most common gaseous substances people encounter, including the most common one, air itself, are homogeneous mixtures. The air that you breathe is a homogeneous mixture of oxygen, nitrogen, argon, and carbon dioxide, along with other elements in smaller amounts. Because each layer of the Earth's atmosphere has a different density, each layer of air is its own homogeneous mixture.

Natural gas is a gaseous heterogeneous mixture of methane and other hydrocarbons used as a fuel.In chemistrya mixture is a material made up of two or more different substances which are physically combined. Mixtures are one product of mechanically blending or mixing chemical substances such as elements and compoundswithout chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup.

Some mixtures can be separated into their components by using physical mechanical or thermal means. Azeotropes are one kind of mixture that usually poses considerable difficulties regarding the separation processes required to obtain their constituents physical or chemical processes or, even a blend of them. Mixtures can be characterized by being separable by mechanical means e. A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water.

A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water. One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution. Mixtures can have any amounts of ingredients.

The following table shows the main properties of the three families of mixtures and examples of the three types of mixture.

A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample and is also referred to as solutions. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample and also has 2 variations also known as colloid and suspension. In chemistryif the volume of a homogeneous suspension is divided in half, the same amount of material is suspended in both halves of the substance.

An example of a homogeneous mixture is air. In physical chemistry and materials science this refers to substances and mixtures which are in a single phase. This is in contrast to a substance that is heterogeneous. A solution is a special type of homogeneous mixture where the ratio of solute to solvent remains the same throughout the solution and the particles are not visible with the naked eye, even if homogenized with multiple sources.

In solutions, solutes will not settle out after any period of time and they can't be removed by physical methods, such as a filter or centrifuge. Air can be more specifically described as a gaseous solution oxygen and other gases dissolved in the major component, nitrogen.

Since interactions between molecules play almost no role, dilute gases form trivial solutions. In part of the literature, they are not even classified as solutions. In gas, intermolecular space is the greatest—and intermolecular force of attraction is least. Some examples can be oxygen, hydrogen, or nitrogen. In chemistry, a mixture is a substance containing two or more elements or compounds that are not covalently bound to each other and retain their own chemical and physical identities—a substance which has two or more constituent physical substances.

Mixtures, in the broader sense, are two or more substances physically in the same place, but these are not chemically combined, therefore ratios are not necessarily considered. An example of a solid homogeneous mixture is bronze, which is a mixture of copper and tin. Most of the food we eat is a combination of different things. Rarely do we eat only one ingredient. For example, we can eat plain chicken, but why not mix it with a little seasoning?

Here are more examples of mixtures as they relate to one of American's favorite pastimes: eating.
