WebThe colloidal solution are metals are obtained by this method, The metal, whose sol is to be prepared, is made as two electrodes in a dispersion medium such as water. The dispersion medium is kept cool by surrounding it with a freezing mixture. An electric arc is struck between the electrodes. The tremendous heat generated by the arc vaporised ... WebSolution. Bredig's arc method consists of both dispersion and condensation. An arc is struck between electrodes, under the surface of water containing some stabilizing agent such as traces of KOH (potassium hydroxide). The intense heat of the arc vaporizes (Dispersion) some of the metal which then condenses under cold water.
