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
test tubes
transfer pipettes
Gatorade
Starch solution10 g/1000 ml water
Benedict¹s Solution
Iodine…
