Heterogeneous Aqueous Solutions Section 17.4

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

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

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

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

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

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