Vedclass · Answer

(C) Lyophilic colloids are characterized by a strong affinity between the dispersed phase and the dispersion medium.They are stable and are not easily precipitated by small amounts of electrolytes; a large amount of electrolyte is required to cause coagulation (salting out).They are reversible in nature,meaning they can be reformed after evaporation of the dispersion medium.They are not easily visible under an ultramicroscope due to the small size and high solvation of particles.

Which of the following is a characteristic of a lyophilic colloid?
