4. Write a scheme of the micelle structure for sol: a) Silver chloride, stabilized by sodium chloride b) Lead (II) chloride, stabilized by potassium chloride c) Iron (III) hydroxide, prepared by adsorption peptization; peptizing agent - iron (III) chloride d) Prussian blue, stabilized by potassium hexacyanoferrate (II) 5. What are the features of the molecular kinetic and optical properties of colloidal dispersed systems? 6. Coagulation of 1.5 L of gold sulfide sol occurred after addition of 570 mL of a 0.2 M sodium chloride solution. Calculate the coagulation threshold of a sol with sodium ions 7. The coagulation threshold of the sol by 0.1M potassium dichromate solution is 0.063 mol/L. Calculate the volume of this electrolyte, which must be added to 10 liters of aluminum hydroxide sol to cause its coagulation.

Fill in the scheme for acid-base extraction and separation of a three-component mixture of 1, 2, and 3. Place the letter corresponding to each step in the boxes below, draw the structures where necessary and marked at the end what layer your final product is in. Each letter may be used once, more than once or not at all. (Each box may contain 1-3 letter.)

On the basis of the general solubility rules given in Table $7.1,$ write a balanced molecular equation for the precipitation reactions that take place when the following aqueous solutions are mixed. Underline the formula of the precipitate (solid) that forms. If no precipitation reaction is likely for the reactants given, explain why. a. ammonium chloride, $\mathrm{NH}_{4} \mathrm{Cl}$, and sulfuric acid, $\mathrm{H}_{2} \mathrm{SO}_{4}$ b. potassium carbonate, $\mathrm{K}_{2} \mathrm{CO}_{3},$ and tin(IV) chloride, $\mathrm{SnCl}_{4}$ c. ammonium chloride, $\mathrm{NH}_{4} \mathrm{Cl}$, and lead(II) nitrate, $\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}$ d. copper(II) sulfate, $\mathrm{CuSO}_{4}$, and potassium hydroxide, $\mathrm{KOH}$ e. sodium phosphate, $\mathrm{Na}_{3} \mathrm{PO}_{4},$ and chromium(III) chloride, $\mathrm{CrCl}_{3}$ f. ammonium sulfide, $\left(\mathrm{NH}_{4}\right)_{2} \mathrm{~S},$ and iron(III) chloride, $\mathrm{FeCl}_{3}$
