Product description
- Determine the height at which, after establishing diffusion-sedimentation equilibrium, the concentration of SiO2 hydrosol particles will decrease by half. The sol particles have a spherical shape, the particle dispersion is equal to:
a) 0.2 nm-1;
b) 0.1 nm-1;
c) 0.01 nm-1.
The density of SiO2 is 2.2 g/cm3, the density of water is ρ0 = 1 g/cm3, the temperature T = 298 K.
