1. Colloids, Solutions, Suspensions The three kinds of mixtures are distinguished by the size of the particles that make them up. ? ? ? ?

2. Solutions A homogeneous mixture containing a solvent and 1 or more solutes Solvents can be gases, liquids, or solids. Solutes can be gases, liquids or solids. The solution has the same physical state as the solvent.

3. Solutions Common examples Lemonade carbonated water vinegar rubbing alcohol food coloring the air we breathe, sea water

4. Colloids A mixture containing small, undissolved particles that do not settle out. Contains larger particles than a solution Particles are still too small to be seen, but are large enough to scatter a light beam

5. Colloids Common examples: Mayonaise Jello Fog, clouds Smoke Milk Whipped cream

6. Suspensions A mixture in which particles can be seen and easily separated by sedimentation or filtration. – Ex. Sand and water – Does not have the same properties throughout (heterogeneous) – Particles in a suspension are larger than the particles in solutions and colloids

7. Suspensions Common examples Mud or muddy water, is where soil, clay, or silt particles are suspended in water Flour suspended in water Paint Chalk powder suspended in water Dust particles suspended in air Algae in water
