Part A: Testing Permeability to Starch and lodine
1. Put on your goggles, apron, and gloves.
2. Add 50 mL of water to a 250-mL beaker.
3. Cut a 15-cm length of dialysis tubing. Soak the tubing in the water for one minute.
4. Remove the tubing from the water. Fold up 1 or 2 cm of the tubing at one end. Cut a piece of
string to tightly seal off the folded end. Roll the unsealed end of the tubing between your
fingers until it opens.
5. Based on your knowledge of starch, do you predict that starch will diffuse through the tubing?
Why or why not? Record your prediction and explanation below.
6. Use one of the droppers to add about 5 to 8 mL of starch solution into the tubing.
7. Fold down 1 or 2 cm of the tubing at the open end. Cut a second piece of string to tightly seal
this end.
8. Use tap water to thoroughly rinse the outside of the tubing. Be sure to rinse the stringas
well.
9. Place the tubing in the beaker. Most or all of the tubing should be covered with water.
