Homeogeneous mixtures, Heterogeneous
mixtures, and separation techniques...
(Get out your notes...)
1
Heterogeneous Mixture - Not uniform
(a sample from the top will be different
from a sample from the bottom.)
2
Homogeneous Mixture - Uniform (a
sample from the top will be the same
as a sample from the bottom.
3
Solutions: A special type of
homogeneous mixture...
One substance is dissolved in
another in a liquid phase.

5
Methods for separating a mixture
6
Filtration: separating by particle
size leaving solids behind.
7
-
Decanting: Pouring off a liquid to
keep a solid behind
8
Distillation: separation by boiling
points
9
Manual Separation: Picking the stuff out.

Your Task:
Design a procedure to separate out a mixture
of substances...
Assume that you will need to use all of the
processes you have seen...
