WHO AM I?
Mixtures: Heterogeneous or Homogeneous
1. I exist in more than one phase and settle into layers.
2. My particles scatter light.
3. I am negative for the Tyndall effect.
4. My particles are so small that they are not visible and
cannot be filtered out.
5. I am also known as a solution.
6. My components are distinguishable and will separate
into phases.
7. I tend to appear cloudy.

WHO AM I?
Mixtures: Suspensions, Colloids, or Solutions
1. My particles are of intermediate size but cannot be
filtered out.
2. I often appear cloudy because my particles remain
suspended rather than completely dissolving.
3. When I am liquid, I am clear and transparent.
4. My particles are large and usually visible.
5. My particles can be separated by filtration or
centrifuging.
6. My composition is uniform and exists in a single phase.
7. My particles are too small for filtration but can be
separated by distillation.

WHO AM I?
Substances: Elements or Compounds
1. My chemical formula reflects only one type of atom.
2. I am found on the Periodic Table.
3. I can be broken down into simpler substances by
chemical means but not by physical means.
4. My properties are very different from those of my
separate parts.
5. I have a chemical formula.
