Collidal dispersion have been classified into different types depending upon the physical state of the dispersed phases 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 or the egg dissolved into water.C. Common salt added into benzene.D. Stannous chloride solution added to gold chloride solution.
