The document discusses the process of decantation to separate mixtures. Decantation involves either allowing solids to settle and pouring off the liquid or allowing immiscible liquids to separate based on density, with the lighter liquid poured or siphoned off. It provides examples of mixtures that can be separated via decantation, such as oil and vinegar, as well as examples that cannot be separated this way, such as rice and water. The purpose is to obtain a decant or precipitate free of particulates.

6. Separating Liquids and Solids
Allowing the solids to settle to the bottom of the
mixture and pouring off the particle-free part of
the liquid.
Separating Two or More Liquids
Allowing two immiscible liquids to separate and
the lighter liquid is poured or siphoned off.
