I learned today how to prepare Iodine in Potassium iodide. It is simple and easy. All you need is crystal iodine and Potassium iodide. Add 0.5 gram of Iodine and 0.5 gram of Potassium iodide, then dissolve it in 50 ml of distilled water. After that, still the solution until it is completely dissolved. At the end, u will get a brownish color of a mixture of Iodine in Potassium iodide.
