solution →

soluble →
a substance that will dissolve.
insoluble →

filtration =
separates substances that are insoluble in a solvent from those that are soluble.
crystallisation =
separates a soluble substance from a solvent by evaporation.
simple distillation =
separates a liquid from a mixture by evaporation followed by condensetion.
fractional distillation =
separates a mixture of liquids whose boiling points are similar.
chromatography =
separates small amounts of dissolved substances by running a solvent along absorbent paper.
