How many of the statements are incorrect? (I) Lyophobic are self stabilized. (II) For a protective colloid, the higher the gold number the greater its protecting power. (III) 0.025 g of a protective colloid is needed to prevent coagulation of 10 mL standard gold sol on addition of 1 mL of 10 % NaCl solution, then its gold no. is 0.025 . (IV) Lyophilic sols are more stable than lyophobic sols due to solvation of colloidal particles.
