During dialysis
1) only solvent can diffuse
2) all kinds of particle can diffuse through semipermeable membrane
3) solvent and ions can diffuse
4) solvent,ions , colloidal particles can diffuse
DEAR STUDENT,
Dialysis is a process used to separate colloidal particles from dissolved ions or molecules. When a colloidal mixture is placed in a semipermeable membrane, which is then placed in an aqueous solution or pure water, dissolved ions and small molecules are allowed to pass through this membrane. This causes colloidal particles to stay in the membrane because these particles are unable to pass through the small pores of the membrane. The principle of dialysis is based upon the fact that colloidal particles cannot pass through a parchment or cellophane membrane while the ions of the electrolyte can pass through it. Thus, option(c) solvent and ions can diffuse is the correct answer.
