Why can dialysis tubing be used to simulate diffusion through a selectively perm

Question

Why can dialysis tubing be used to simulate diffusion through a selectively permeable membrane? In exercise 2A (Osmotic Behavior of Animal Cells) the question is:How will red blood cells (RBC) behave when exposed to hypotonic, hypertonic, and isotonic solutions? Write a property worded hypothesis for each condition. a. How will RBCs behave when placed in isotonic media? b. How will RBCs behave when placed in hypotonic media? c. How will RBCs behave when placed in hypertonic media? Write a specific prediction based on your hypothesis for each condition using the IF/THEN form IF In exercise 2 B the question is:How will Elodea cells behave when exposed to hypotonic, hypertonic, and isotonic solutions? Write a properly worded hypothesis for each condition. a. How will Elodea cells behave when placed in isotonic media? b. How will Elodea cells behave when placed in hypotonic media? c. How will Elodea cells behave when placed in hypertonic media? Write a specific prediction based on your hypothesis for each condition using the IF/THEN form

Explanation / Answer

4) Dialysing tubing is also called as Visking tubing. Dialysing tubing membrane is a semi-permeable membrane that is used in different seperation techniques. It facilitates the removal or exchange of small molecules from the solution by means of differential diffusion. Dialysing tubing is also used in the demonsatration of osmosis and movement of molecules across a selectively permeable membrane. Because of these properties of dialysing tubing, it is used to simulate diffusion through a selectively permeable membrane.
