How do you separate a mixture?

Answer 1

The 2 simple ways are using a filter or heating it to cause evaporation.

A mixture is a combination of two (or more) substances that are not chemically joined together. Parts of a mixture with different properties will act differently when changed in the same way. So you can use a physical change to push, pull, lift, or otherwise separate one part of a mixture from another. They can be easily separated from one another by physical means (heat, electromagnetism, filtration, distillation, or centrifuge)

You need to find a physical attribute that is different for each component of the mixture. The most common example is a mixture of salt and sand where you add the mixture to water thus dissolving the salt. You then filter out the sand leaving the salt solution. You then evaporate the water from the solution leaving the salt.

Density, solubility, particle size, magnetism, melting points, and boiling points are all good properties to use when separating mixtures. If two liquids have two different boiling points, you can use distillation. You can also separate liquids, or the particles in liquids, using chromatography. You can also use a screen or filter.

Some physical methods of separating mixtures:

1. Magnetism - a magnet can be used to separate iron from sand, but not necessarily iron oxide)
2. Filtration - liquids and anything dissolved in the liquid passes through holes in the filter paper but the solid particles are too big and get stuck.

   (filters can be used to separate dirt and rock from water)

3. Evaporation by heating can separate a dissolved solid solute from a solution.
4. Solution - salt can be removed from sand by dissolving in water
5. Distillation - can be used to separate liquids that have different boiling points.
6. Sedimentation - by freezing water, dissolved solutes will precipitate
7. Centrifugation - high-speed spinning forces heavier substances to the outside
8. Sieving - separates solids by grain size

Answer 2

Depending up on the size of particles of different matters in a mixture each component can be separated by using an appropriate size of seive. 2. By providing elctromegnetic fields of variable strength. 3. By using solvents and 4. by gravitational force like blowing with the wind velocity etc.

Answer 3

Settling. Filtering. Centrifuging. Fractional distillation.

Answer 4

No general answer is possible, because it depends on the components of the mixture!

Answer 5

distillation,crystallization,sublimation,filteration, etc
