43. Solution to Chemistry Problem
7. Aggregate-stable monodisperse silver hydrosol is kept at 25 C in a cylindrical vessel until sedimentation-diffusion equilibrium is established. The surface area of the vessel bottom S is 10 cm2, the height of the sol layer H = 6 cm, the total content of the dispersed phase m = 0.3 g. Calculate the concentration of the dispersed phase in kg/m3 at a height of 3 cm. The radius of the particles r = 7 nm, the density of the particles p = 10.5 g/cm3, the density of the dispersion medium po = 1 g/cm. The viscosity of the medium is 10-3 Pa*s.
