Question

Why osmotic pressure of colloidal.Solution os smaller than true.Solution?

Answer 1

Answer:

Explanation:

For the high molecular weight of particles, the number of molecules in a colloidal solution is small compared to those in a true solution and thus the osmotic pressure of a colloidal solutions may be very low and cannot be accurately measured.

Answer 2

Osmotic properties. ... For the high molecular weight of particles, the number of molecules in a colloidal solution is small compared to those in a true solution and thus the osmotic pressure of a colloidal solutions may be very low and cannot be accurately measured.
