Vedclass · Answer

(A) Hydrophilic sols are lyophilic colloids where the dispersed phase has a strong affinity for the dispersion medium $(H_2O)$.When a hydrophilic substance is dissolved in water,it interacts with the water molecules,which reduces the cohesive forces between the water molecules at the surface.Since surface tension is a result of these cohesive forces,the addition of a hydrophilic solute decreases the surface tension of the solvent.Therefore,the surface tension of a hydrophilic sol is less than that of pure $H_2O$.
