So sorry! Potassium iodide is on backorder from our supplier. We expect to have it in stock by March 1.
A white, crystalline powder that is mixed with water and soap to produce a concentrated solution. When this solution is added to a bottle with 30% hydrogen peroxide, the peroxide decomposes and releases large amounts of oxygen and heat. Excellent demonstration of how color, heat, odor and state all indicate a chemical change.
