the protective power of the lyophilic co...

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.
On addition of one mL of sloution of 10 % NaCl to 10 mL. of red gold sol in presence of 0l.025 g of starch the coagultion is just prevented . the gold number of starch is
