Expert Answer
Electro-disintegration ( Bredig’s method):
- This process involves dispersion as well as condensation.
- This method is mainly used for obtaining colloidal solutions of metals like gold, silver, platinum, etc.
- An electric arc is struck between the two metallic electrodes suspended in a dispersion medium.
- 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.
