Product description
- Arsenic sulfide hydrosol contains 7.2 kg of As2S3 in 1 m3 of sol. The average diameter of the particles is 2•10-8 m. Calculate: a) the partial concentration of the hydrosol and its osmotic pressure at 273 K, if the density of solid arsenic sulfide is 2.8•103 kg/m3; b) the partial concentration of the hydrosol and its osmotic pressure, assuming that arsenic sulfide forms a true solution of the same mass concentration. How many times is the osmotic pressure of the hydrosol less than the osmotic pressure of the supposed true solution?
