This potassium iodide (KI) is lab grade and in crystalline form. Use this chemical in science experiments requiring potassium iodide crystals, such as the famous "Elephant Toothpaste" foaming reaction demonstration. (You can also get a complete Elephant Toothpaste Science Kit that comes with 10 g of potassium iodide crystals.) You can also use it to conduct other laboratory procedures that require potassium iodide crystals.
Did you know KI is a stable iodine salt that can help protect the thyroid from radiation absorption? (Note that these crystals are for science lab use only!)
