In the Dialysis Tubing Experiment, why did the water turn blue?

• Starch went into the dialysis tubing through osmosis

• The long chained carbohydrate was too large to get into the dialysis tubing.

• The iodine osmosed through the tubing and a chemical reaction occurred between the iodine and the corn starch

• The iodine diffused through the tubing and a chemical reaction occurred between the iodine and the corn starch
