100 mL of a standard sol required 240 mg of starch for its protection against coagulation, Calculate gold number of starch.

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
