The Effect of Concentrations of Starch and Sugar Solutions on Synthetic Semi-Permeable Membranes

Hope you injoy my science project very good The Effect of Concentrations of Starch and Sugar Solutions on Synthetic Semi-Permeable Membranes By: Jamie Hardy Question: Is dialysis tubing selectively permeable? Hypothesis: If one has dialysis tubing, which is dipped in water, filled with Gatorade and starch and is left for 15 minutes, the sugar in the Gatorade will exit the dialysis and into the water. So the dialysis is semi-permeable. Materials: 16 cm dialysis tubing beaker cylinder …

…very dull baby powder. When the Gatorade solution was placed over the flame the solution bubbled to the top of the test tube and almost went over. Conclusion: My hypothesis, "If one has dialysis tubing, which is dipped in water, filled with Gatorade and starch and is left for 15 minutes, the sugar in the Gatorade will exit the dialysis and into the water. So the dialysis is semi-permeable.", was proven correct. The tubing is semi-permeable.
