Colloid dispersions exhibit several properties. Among these are the scattering of a light beam directed through a colloidal dispersion. This is known as the Tyndall effect and its magnitude is due to the size and number of particles present.yup

Properties of a colloid

  • A colloid is a heterogeneous mixture.
  • The size of particles of a colloid is too small to be individually seen by unaided eye.
  • Colloids are big enough to scatter a beam of light passing through it and make its path visible.
  • They do not settle down when left undisturbed, that is, a colloid is quite stable.
