Iodine is a non-metallic element which has applications in fields ranging from medicine to the arts in its crystalline form. Finding naturally occurring iodine crystals is difficult ,as they only grow in very small groups. You can separate an iodine liquid to extract the crystals. You can extract whatever quantity of solution at a time, but working in larger quantities yields the most crystals.
Instructions
1. Pour four bottles of tincture of iodine into a mixing flask. Use the standard small sized bottles.
2. Add enough water to the flask to double the volume of liquid within. Stir the water and tincture to combine.
3. Pour 20 ml of hydrochloric acid into the iodine solution. Add 40 ml of bleach into the flask and stir everything thoroughly.
4. Turn two paper coffee filters upside down and set them over the mouth of a beaker. If the filters are very thin, use an extra one or two to avoid having the filter deteriorate during extraction.
5. Pour the mixture from the flask into the beaker, using the filters as a sieve. The crystals will remain out of the beaker by sitting on top of the filter.
