1. Solutions, Suspensions, and Colloids

2. Solutions
Made of very small particles (hard to see even with microscope)
Particles will never settle to the bottom of the container
Remains uniformly mixed (only see 1 thing) – same color, density
Ex: salt water, kool-aid, rubbing alcohol, pop, gasoline

3. Solutions Solute = substance being dissolved
Solvent = substance doing the dissolving
Ex: Kool-Aid
solute = sugar
solvent = water

4. Solutions

5. Suspensions Made of large particles
A liquid in which visible particles settle to the bottom of the container
Ex: muddy water, glacial meltwater, blood

6. Suspensions

7. Colloids Medium-sized particles
Particles will not settle to the bottom of the container
Particles scatter light
Ex: milk, gelatin, fog (headlights in fog)

8. Colloids

9. Put it all together…. Settle upon standing?
