Vedclass · Answer

(D) The statement in option $D$ is false because lyophilic sols are inherently stable due to strong interaction between the dispersed phase and the dispersion medium. They cannot be easily coagulated by adding small amounts of an electrolyte. Coagulation of lyophilic sols requires the addition of a large amount of electrolyte or the addition of a suitable solvent (like alcohol or acetone) to dehydrate the particles. In contrast,lyophobic sols are unstable and are easily coagulated by adding small amounts of an electrolyte. Latex is a colloidal solution of rubber particles which are negatively charged,but since the question asks for the false statement,$D$ is the most scientifically inaccurate statement regarding the ease of coagulation.
