▪ Separating solids from liquids.
▪ It requires a filtering medium like cheesecloth or filter
paper, which traps the insoluble substances while
allowing the liquid that contains the soluble substances
to pass through.
▪ Is a process used to separate the components
of mixture based on their varying eights.
▪ Heavy suspended particles are allowed to
settle at the bottom of the container.
▪ To poured out carefully a liquid, leaving
another liquid or solid behind.
▪ Takes advantage of differences in
density.
▪ Is the process of separating a soluble solid to a liquid
or solvent.
▪ In this process, the solution is subject to heat until the
liquid (solvent) evaporates and the solid will be left.
▪ Is the separation of mixtures through the continues
cycle of evaporation and condensation of the volatile
components of the mixture, which have different
boiling points..
▪ Is a simple but efficient used to separate and identify
the components of mixture.
▪ Separation takes place because the components of a
mixture have different affinities for the two phases, the
stationary phase and mobile phase.
