Answer:
Decantation
Explanation:
Decantation is a process to separate
mixtures by removing a liquid layer that
is free of a precipitate, or the solids
deposited from a solution. The purpose
may be to obtain a decant (liquid free
from particulates) or to recover the
precipitate.
Decantation relies on gravity to pull
precipitate out of the solution, so there is
always some loss of product, either from
the precipitate not fully falling out of the
solution or from liquid remaining when
separating it from the solid portion.
The Decanter
A piece of glassware called a decanter is
used to perform decantation. There are
several decanter designs. A simple
version is a wine decanter, which has a
wide body and a narrow neck. When
wine is poured, solids stay in the base of
the decanter.
In the case of wine, the solid is usually
potassium bitartrate crystals. For
chemistry separations, a decanter may
have a stopcock or valve to drain the
precipitate or dense liquid, or it may
have a partition to separate fractions.
Use of Alum and filtration process can also be administered for further purification
