During dialysis
Only solvent molecules can diffuse
Solvent molecules, ions and colloidal particles can diffuse
All kinds of particles can diffuse through the semipermeable membrane
_____________arises due to the fact that the surface particles of the adsorbent are not in the same environment as the particles inside the bulk.
Absorption
Adsorption
desorption
Sorption
