Simple Separation Techniques SST

Simple Separation Techniques (SST) Processes that
are used to separate mixtures 1. Fractional
Distillation separation of 2 or more liquids
based on their boiling points 2.
Sieving/Screening separation of solids based on
size 3. Flotation separation of solids based
on density (add water to the solid mixture and
skim off the substance that is less dense than
water) 4. Paper Chromatography used to
separate inks or dyes

5. Filtration separation of solids based on
solubility (one soluble, one insoluble filter
solution and boil off liquid to collect dissolved
solid) a. precipitate - remains in filter
paper b. filtrate - substance that goes through
filter paper 6. Fractional Crystallization
separation of solids based on solubility at
different temperatures (heat solution containing
different substances so one solid dissolves and
the other does not filter and cool) 7. CCD -
separation of gases based on their
condensation/boiling point (cool the gas,
condense it into a liquid and distill it)
