Vedclass · Answer

(D) The stability of lyophilic sols is primarily due to two factors: the charge on the colloidal particles and the solvation (hydration) of the particles. To make a lyophilic sol unstable (i.e.,to cause coagulation),both of these stabilizing factors must be removed. This is achieved by adding a suitable solvent (like alcohol or acetone) to dehydrate the particles and by adding an electrolyte to neutralize the charge. Therefore,the addition of both alcohol and an electrolyte makes the lyophilic solution unstable.
