Which method of colloid purification uses a phenomenon of diffusion through a permeable membrane? Correct Answer Dialysis

Dialysis is a method of purification of colloidal solutions from which ions are removed by diffusion through a permeable membrane. Example: – Ferric hydroxide sol can be purified using this method.

In a gas mixture of hydrogen and oxygen, steady state equimolar counter diffusion is occurring at a total pressure of 100 kPa and temperature of 20°C. If the partial pressures of oxygen at two planes 0.01 m apart, and perpendicular to the direction of diffusion are 15 kPa and 5 kPa, respectively and the mass diffusion flux of oxygen in the mixture is 1.6 * 10–5 kmol/m2.sec, calculate the molecular diffusivity for the system. For equimolar counter current diffusion:

Assertion (A) In osmosis, solvent molecules pass through a semipermeable membrane from a more dilute solution to a more concentrated one, when these two are separated by the semi-permeable membrane.
Reason (R) The vapour pressure of the solvent over the dilute solution is less than that over the concentrated solution.
