Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound
