distillation or filtration (GCSE chemistry)

since simple distillation can also be used to separate solids (insoluble/soluble) from liquids, can filtration used instead if the solid is insoluble in water?

thanks :smile:

Yes, filtration can be used in this case.

also, why does fractional distillation put glass beads in the fractionating column and not during simple distillation (mixture of 2 liquids)? Is it because that it is used to separate liquids that are more close, in terms of boiling points? If so, why do they say that it is used for 3 or more liquids? couldnt it be used to separate 2 liquids too, if their boiling points are similar?

It’s not something you need to know for GCSE, but the beads provide a place for vapours to condense, then boil again, effectively distilling it multiple times over. The higher up the beads are, the less easily the higher boiling fractions get redistilled and therefore the better the separation.
