Editor's Notes

  1. A suspension is a heterogeneous mixture. Suspended particles can be removed by filtration. Comparing and Contrasting How does the filtration of a suspension compare with the filtration of a solution?
  2. The path of light is visible only when the light is scattered by particles. a) Fog or mist is a colloid and thus exhibits the Tyndall effect. b) Particles in colloids and suspensions reflect or scatter light in all directions. Solutions do not scatter light.
