Expert Answer:

 Electro-disintegration ( Bredig’s method):

  1. This process involves dispersion as well as condensation.
  2. This method is mainly used for obtaining colloidal solutions of metals like gold, silver, platinum, etc.
  3. An electric arc is struck between the two metallic electrodes suspended in a dispersion medium.
  4. The high heat of arc converts the metal into vapours which are condensed immediately in the ice cold water bath giving the particles of colloidal size.
