Question

What will happen if you take exactly 2 grams of corn starch, put it in a small bag, add 100mLs of water then close the bag completely. then submerge the bag in a bowl full of water and 20 drops of Iodine for 4 days?

Answer 1

The water which contains the iodine would be blue-black in colour. Now via process of osmosis the water containing the iodine would enter the bag. The iodine in the water would react with the starch to forming a purple solution.
