Lyophilic colloidal dispersion
WebJul 25, 2024 · Definition of Lyophilic Colloids. These colloids are said to the solvent-loving, as these colloids have a distinct attraction towards dispersion medium.When lyophilic colloids are mixed with the liquids, the strong force of attraction arises between liquid and colloidal particles which results in the formation of such a stable solution. WebLyophilic sol is simply created by combining a colloid with a liquid solvent. Stability is achieved primarily by applying an electric charge to the dispersed particles and surrounding each particle with a protective solvent sheath that inhibits mutual adhesion when the particles collide due to Brownian movement.
