Different boiling points - Apex 2015
It is the combination of different solubilities and the different adhesions of the solutes to the medium.
different molecular sizes
The solution is absorbed onto a piece of paper
Substances with different densities will separate into layers.
Distillation depends on differences in boiling and condensing temperatures of the mixture being distilled
In solution, the salt will be dissolved in the water, the sand and iron will settle to the bottom of the container. Separate out the water, evaporate the water and the salt will remain, separate the sand and iron filings with a magnet.
There is one very big difference between a mixture and a solution. Mixtures can be separated into parts physically where solutions cannot.

Distillation depends on differences in boiling and condensing temperatures of the mixture being distilled
Distillation is based on the differences of boiling points of substances.
Filtration of a solution can only remove the insoluble substances.

There are a number of different ways to separate the parts of a mixture of liquids. Since the liquids in question usually have different boiling points, they can be separated by means of distillation. If they have significantly different densities, it may be possible to separate them be means of a centrifuge. The liquid can be poured onto paper and separated by means of chromatography, based on the different rates at which different substances diffuse through paper. In some cases freezing, rather than boiling, can be used as a means of distillation.

A centrifuge might separate out a mixture if the particles that are mixed together are of significantly different sizes/densities, but other than that there aren't any good ways to mechanically separate out a mixture. The answer is filtration because filtrarion seperates the two things after filtrated.... (eg: water and bacteria are a mixture, but if you filtrate them, the 2 substances separate making them unmixtured.) ..... the answer again is filtrate.
