Day 7

Spaced Revision

Come back to Colloids after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • True solution: particle size < 1 nm
  • Colloid: particle size 1–100 nm
  • Suspension: particle size > 100 nm
  • Dispersed phase: the colloidal particles
  • Dispersion medium: the substance in which particles are dispersed
  • Eight types of colloids possible based on physical states
  • Lyophilic: reversible, stable, solvent-loving
  • Lyophobic: irreversible, less stable, solvent-hating
  • Macromolecular: large single molecules (e.g., proteins)

Common Mistakes to Avoid

Colloids are homogeneous like true solutions because they look uniform.

The dispersed phase is always solid and the dispersion medium is always liquid.

All colloids can be filtered using ordinary filter paper.
