Colloids, Solutions, Suspensions

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

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.

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

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

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

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

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
