Detailed explanation-1: -The substance which move out of the dialysis dialysis bag is water molecule or solvent. And the solvent molecules like small molecules ions, amino acid and glucose move into the dialysis bag.

Detailed explanation-2: -Dialysis is the separation of smaller molecules from larger molecules in solution by selective diffusion through a semipermeable membrane. Dialysis tubing will be used in this laboratory to simulate a cell membrane. It is made of selectively permeable cellulose tubing perforated with microscopic pores.

Detailed explanation-3: -Dialysis tubing for laboratory use is typically made of a film of regenerated cellulose or cellulose ester. However; dialysis membranes made of polysulfone, polyethersulfone (PES), etched polycarbonate, or collagen are also extensively used for specific medical, food, or water treatment applications.

Detailed explanation-4: -The dialysis tubing we are using allows the passage of molecules smaller than 14000 daltons.
