Which substances (glucose, IKI indicator, starch) diffused across the dialysis tubing membrane?
Added by Lance R.
Step 1
Glucose is a small molecule that can easily pass through the dialysis tubing membrane. IKI (iodine-potassium iodide) indicator is used to test for the presence of starch and can also diffuse through the membrane. Starch, on the other hand, is a larger molecule and Show more…

During an experiment, you set up a dialysis bag with a solution of glucose and starch inside of it. You then placed this bag into a solution of I2KI. Which compounds moved across the semi-permeable membrane of the bag? Why were they able to cross the membrane?

For this series we will imagine you've placed solutions of glucose and starch into a dialysis tubing bag and then put the bag into a beaker of IKI in water. The dialysis bag is made of cellulose and has small pores that allow movement of small molecules but not large molecules. The images below show this arrangement. Note the tubing has been tied off on both ends; movement of molecules across the tubing then must use the pores. Also note that there are no proteins present. How large are the molecules we're using? Small molecules include water, glucose, and IKI. Large molecules include starch. BEFORE EXPERIMENT AFTER EXPERIMENT 1) Based on the left image above (before any movement has happened), what molecule(s) besides water is/are in the beaker compartment (top arrow)? What molecule(s) is/are in the bag compartment (lower arrow)? Now allow the experiment to proceed to equilibrium where no net movement will occur. Based on the right image above (after all movement has happened), what molecule(s) besides water is/are in the beaker compartment (top arrow)? What molecule(s) is/are in the bag compartment (lower arrow)? If you test the bag and the beaker solution will the IKI show the presence of starch in either compartment? What about the Benedict's test: will it show the presence of glucose in either compartment?
