How did you separate the solids from the liquids?

Answer 1

Err, well Solids are called Solids because there solid (unbreakable) unless you burn (melt) the solid but this can only work with some solids eg plastic, also sometimes you can snap solids eg Chocolate bar. But most Solids are not separatable. You could also use things like magnets which sort of attach things that are metal- only works if things are metal.

Solids can dissolve in solutions. For examples sugar dissolve in water.

Now lets take a mixture of two solids for example sand and sugar.

If you mix sand with water it doesn't dissolve. However the sugar will.

If you put your sand/sugar mixture in water, the sand will still be in the solid form but the sugar will be in solution (dissolved in water).

To get the sand you just need to filter the solution (a bit like when you cook pasta and get rid of the water by sieving it). You will get the solid sand in on your filter paper.

You also can get the sugar back. After filtering, only sugar will be remianing in solution. By evaporating the water, solid crystals of sugar will appear.

Et voila! That's how you can separate two solids.

When two solids dissolve in the same solvents, that becomes more complicated. As the person who answered before me said, sometimes you can use magnets....

Answer 2

Like iron and sulphur. when you mix them together and you can take the iron out by using a magnet. But if you heat them both together, it will be a new substance; iron-sulphur, which you cannot take iron out by a magnet

Answer 3

Solids can often be removed from a liquid by filtering the liquid, or by settling, where solids either settle to the bottom or float to the top.
