Syllabus statement 1.7 and 1.8 Last post I was talking about elements, compounds and mixtures and how there is a whole big chapter on separating mixtures. Well here's the post on separating mixtures. There are a bunch of different mixtures you could have so I'll separate it up for you. If you have a solid and a solid: Is one solid magnetic? It can be removed by a magnet Does one dissolve in water? Add water, remove the insoluble solid and evaporate the water to get the soluble solid. Does one float and one sink? You can scoop the solid that floats off the top and filter the solid that sinks. If you have a liquid and a liquid: Does one have a lower boiling point than the other? You can use distillation to remove the more volatile liquid.
If there is ever a solid and liquid mixture then you only need to filter it. A simple way to find out what a mixture of liquids is for example in pen ink is to do chromatography. Click Read More to find out about Chromatography!
