Presentation Transcript

  1. Heterogeneous Aqueous Solutions Section 17.4

  2. After reading Section 17.4, you should know: • The difference between a suspension, colloid, and solution • How to describe the Tyndall Effect

  3. Suspensions • Mixtures from which particles settle out upon standing. • Heterogeneous • Particle size ~ 1nm • Example – sand and water or muddy water

  4. Colloids • Heterogeneous mixtures containing particles that are intermediate in size between suspensions and solutions • Particle size 1nm – 100nm • Cloudy or milky in appearance • Examples: gelatin, smoke or whipped cream

  5. Colloids demonstrate the Tyndall Effect – scattering of light in all directions

  6. Emulsions – colloidal dispersions of liquids in liquids • Will cause a polar and nonpolar substances to mix

  7. After reading Section 17.4, you should know: • The difference between a suspension, colloid, and solution • How to describe the Tyndall Effect
