Colloidal dispersion have been classified into different types depending upon the physical state of the dispersed phase and the dispersion medium. They are prepared in the industry or in the laboratory by a number of methods and then purified. The protective action of lyophilic colloids was studied by zsigmondy and he introduced a term called gold number Which of the following does not form a lyophilic colloid?

Question

Colloidal dispersion have been classified into different types depending upon the physical state of the dispersed phase and the dispersion medium. They are prepared in the industry or in the laboratory by a number of methods and then purified. The protective action of lyophilic colloids was studied by zsigmondy and he introduced a term called gold number Which of the following does not form a lyophilic colloid? (A) Rubber dissolved in benzene (B) White of the egg dissolved into water (C) Common salt added into benzene (D) Stannous chloride solution added to gold chloride solution

SnCl 2+ AuCl 3 react to form gold sol which is a lyophobic sol

Rubber dissolved in benzene

White of the egg dissolved into water

Common salt added into benzene

Stannous chloride solution added to gold chloride solution

SnCl2​+AuCl3​ react to form gold sol which is a lyophobic sol

$S n C l_{2} + A u C l_{3}$ react to form gold sol which is a lyophobic sol
