Is it possible to separate a homogeneous mixture?

Question

If so, could you give me an example and how to seperate it?

Thank you =]

Answer 1

yes, it is. you have to apply heat. ok.... really simple example... you make a cheese sauce with butter, flour, cheese and milk. the mixture is homogenous. but when you apply a greater amount of heat, the mixture will seperate into curds and fat.

Answer 2

It is usually possible to seperate mixtures whether it is homogeneous or not since a mixture is a substance made by combining two or more different materials in such a way that "no chemical reaction" occurs.

Salt-water solution is a homogeneous mixture, and it can be seperated by natural evaporation or by boiling the liquid mixture.

A homogenous mixture of liquids with different boiling points can be separated by heating it up until it boils and condensing the vapor. The liquid with the lowest boiling point vaporizes and is condensed first; the liquid with the next lowest boiling point vaporizes and is condensed second; and so on. This process is called distillation.

To separate more complicated homogeneous mixtures chemists commonly use a technique called chromatography. There are many different types of chromatography that are used fordifferent types of mixtures. Liquid chromatography (LC), gas chromatography (GC), ion chromatography, paper chromatography, and thin layer chromatography (TLC) are common types. In general, chromatography works by carrying a mixture along a path through a solid material. Some of the substances in the mixture will stick to the solid material more easily and won't travel through as quickly as others. As the mixture travels through the solid, then, the different component substances are separated out as spots or bands. If these substances have colors, so do the spots or bands that show up--hence the name "chromatography."

Answer 4

Use the physical properties of the components to your advantage.

For example, take a teaspoon of sugar and a teaspoon of sand. Mix them together and you have a homogeneous mixture - a single phase, and uniform throughout.

Put the sand/sugar mixture in water and stir it up. The sugar will dissolve.

Filter the sand out of the sugar-water solution, and evaporate the water from this solution.

You now have separated the sand and sugar, to get back to where you started from.

The same can be done for other mixtures, such as air. Cool down air, and the water in the air (humidity) will start to condense. Again, you have separate a homogeneous mixture using the properties of the components.

Answer 5

Yes, by several methods. Performing a chemical reaction/change to make one of them into a solid (allowing it to drop out of the solution) is one way. Distillation is another way, i.e., you can separate alcohols in water based on their boiling points, which exploits a physical difference between compounds. Chromatography can also be use, which exploits the polarity of compounds and their varying attraction to another medium. You can even do chromatography on ionic compounds using ion exchange resins. It all depends on what you are trying to separate, and what differences you can exploit. You can even separate chiral compounds , which are practically identical but are mirror images of one another using a chromatography technique. Every mixture has differences we can exploit...
