…….. Is the gold number of hydrophilic colloid, greater is its protective power.

Gold number of some lyophilic sols are : Which has maximum protective power :

the protective power of the lyophilic colloids es expressed in terms of gold number, a term introduced by Zsigmondy. Gold number is the number of milli - gram of the protective colloid which prevent the coagulation of 10 mLof red gold sol , when 1 mL of a 10 per cent solution of sodium chloride is added to it . thus smaller the gold number of lyophillic colloid, the greater is the protective power. gold number given an indication of
