What happens when persistent dialysis of a colloidal solution is carried out?
उत्तर
When prolonged dialysis of a colloidal solution is done, the colloidal solution in the tube would contain a very small of amount of small solute as most of it will be washed out.
This will lead to concentration of the colloidal particles and coagulation of the solution (colloidal sol)

Assertion: Colloidal solutions show colligative properties.
Reason: Colloidal particles are large in size.
Assertion: Colloidal solutions do not show brownian motion.
Reason: Brownian motion is responsible for stability of sols.
The conditions given below are in the context of observing Tyndall effect in colloidal solutions:
- The diameter of the colloidal particles is comparable to the wavelength of light used.
- The diameter of the colloidal particles is much smaller than the wavelength of light used.
- The diameter of the colloidal particles is much larger than the wavelength of light used.
- The refractive indices of the dispersed phase and the dispersion medium are comparable.
- The dispersed phase has a very different refractive index from the dispersion medium.
