Initially there was a higher concentration of iodine outside than inside the tube …

Can chloride pass through dialysis tubing? Explained by FAQ Blog

Why does starch not pass through dialysis tubing? The starch was impermeable because it would have reacted with the iodine in the water outside the dialysis tubing if it was permeable. … The dialysis tubing is selectively permeable because substances such as water, glucose, and iodine were able to pass through the tubing but the starch …

How did the iodine move into the dialysis tubing? Did it… – Q&A

Iodine moves into the dialysis tubing by diffusion (diffuses through the pores from a region of high concentration to a region of low concentration) across the dialysis tube pores. The starch stayed inside the dialysis tubing because it was too large to pass through the tubing. I knew that it stayed inside because it reacted with the KI …

4 Did water move through the dialysis tubing into or out of the bag …

Include all data for Dialysis and Diffusion in Tables I and II. Water, along with the whole starch solution, moved into the dialysis bag. It unlikely for water to separate itself from the starch solution and move into the bag on its own. The initial mass of the control bag was 16.44 and the final mass was 17.21.

Preparing the “cell” tubing. Retrieve your soaked piece of dialysis tubing and tie a knot in one end as though you are tying a balloon. Using a transfer pipette, half-fill the tubing with your undiluted Starch/Glucose solution and tie the other end to create a “cell”. Submerge the “cell” tubing into the Iodine solution.

(Solved) – Please type your answer. Define diffusion. A glucose-starch …

As dialysis tubing is selectively permeable, both glucose/starch and IKI indicator will pass through the membrane of dialysis tubing. The starch will move into the cup and the IKI indicator will move into the dialysis tube. Since iodine is present in IKI indicator, it will turn both the solutions (in the tube as well as the cup) blue black.
