A mixture of 250 ml of an aqueous solution of methyl orange with a concentration of 0.070 weight. % and 0.209 ml of mineral oil were shaken until an emulsion was formed with an average diameter of oil drops of 4.35 * 10-7 m. As a result of adsorption on the surface of the drops, the concentration of methyl orange in the solution decreased to 0.038 weight. % Calculate the adsorption of G dye. The density of the solution is 0.9982 g / cm3, methyl orange formula: HO3S-C6H4-N = N-C6H4-N (CH3) 2.
