Answer 1

Answer:

4:Decantation

5:It cannot be used to separate two liquids. Decantation is pouring away a liquid from solid impurities which have settled at the bottom of the container. Two liquids with a different density which have separated into two layers can similarly be separated by pouring the less dense liquid out.

6:Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.

7:Decantation is frequently used to purify a liquid by separating it from a suspension of insoluble particles (e.g. in red wine, where the wine is decanted from the potassium bitartrate crystals to avoid unsavory taste). This makes the wine more tonic and astringent.
