The gold number of Galatin . Gum and Starch are 0.005, 0 . 15 and 25 respectively . Which colloid has highest protection 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. On addition of one mL of sloution of 10 % NaCl to 10 mL. of red gold sol in presence of 0.025 g of starch the coagultion is just prevented . the gold number of starch is
