Starch turns a blue-black color in the presence of iodine. Dialysis tubing is a very thin semipermeable membrane. Jayden decides to use this information to test the permeability of some dialysis tubing.
Jayden fills the tubing with a starch solution and places it in a beaker of iodine and water. After two hours, the starch solution in the dialysis tubing turns blue-black. The iodine solution remains the same color (it doesn't change colors).
What do Jayden's results show about the permeability of the tubing?
A.
The dialysis tubing is not permeable to starch or iodine.
B.
The dialysis tubing is permeable to starch but not to iodine.
C.
The dialysis tubing is permeable to iodine but not to starch.
D.
The membrane is permeable to both starch and iodine.
