What are protective colloids? How are the colloids stabilised? Explain the term gold number.

Why are lyophilic colloids used as protective colloids?

Assertion: Gold number is the measure of protective powers of differents colloids. Reason: The smaller the gold number of lyophilic colloid, the smaller is its protective power.

Statement-1:Gold number is the measure of protective powers of different colloids. Statement-2: The smaller the gold number of lyophilic colloid, the smaller is its 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

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

The protective action of different colloids is compared in terms of _________ .
