Presentation Transcript

  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….
