1. Classifying Mixtures

2. Mixtures
• Can be classified by
how well the parts of
the mixture are mixed
• Can be separated by
physical means like
filtration or distillation

3. Heterogeneous Mixtures
Can easily see the
different parts

5. Homogenous Mixtures
A homogeneous
mixture is one that's
mixed or blended
together so well that all of
the ingredients will not
separate out, even over
time.

7. Solutions
• Homogeneous mixture
• Does not separate into
layers over time
• Particles don’t settle
out
• Can’t be filtered
• Don’t scatter light

8. Suspensions
• Heterogeneous mixture
• Separates into layers
over time
• Can use filter to
separate
• Scatter light
• Usually cloudy

9. Colloids
• Considered a
homogeneous mixutre
• Particles in-between a
suspension & a solution
• Do not separate into
layers
• Cannot use a filter to
separate
• Scatter light

10. • What are the main differences between
heterogeneous and homogeneous mixtures?

11. • Is a solution a homogeneous or
heterogeneous mixture?

12. • Is a suspension a homogeneous or
heterogeneous mixture?
•
