In this video, we learn how to make iodine easily. You will need potassium iodine and sulfuric acid to make this. First, add the acid into the potassium iodine slowly. After you add in each part, swirl the beaker slowly so it gets mixed together. After you have added in all of the potassium, you will place this into a beaker filled with ice water while you add in more, because the mixture gets really hot. When finished, you will end up with a mixture that is iodine and nothing else. Fill with water and mix together, then you are finished and can see the iodine!
