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 Not evenly mixed Can easily see the different parts

4. Homogenous Mixtures Evenly mixed Appear as only one substance (like tap water)

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

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

7. 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

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

9. Is a solution a homogeneous or heterogeneous mixture?

10. Is a suspension a homogeneous or heterogeneous mixture?
