  • A colloid is a combination in which one of the ingredients is broken down into extremely small particles and scattered throughout another.
  • A dispersed phase is the material that is scattered, whereas a dispersion medium is the medium in which the initial substance is disseminated.
  • Colloid particles typically range in size from 1 to 1000 nanometres.
  • i.e. 10-5 to 10-7cm
  • 10 – 5 – 10 – 7cm
