Decanting.Decanting involves separating a dense, insoluble substance from a heterogeneous mixture.For example, if we mixed sand with water in a beaker, the sand would not dissolve, but would settle to the bottom, forming a sediment layer.By gently pouring off the water the supernatant, we could separate the sand from it.In the laboratory, using a glass rod can assist the decanting.
Of all the separation techniques you may be asked about, chromatography is the most complicated, and in paper chromatography, it relies on the differences in attractions between the mixture.
