If i place starch and water splution into a membrane and sit it into a container of water/iodine solution the?

because starch is too big a molecule to go thru the membrane, the solution is considered hypertonic, and water will p into the membrane carrying iodine with it. This behavior is kind of like tring to water down the place w/ more solute. Also, the iodine will react w/ starch and change color...
