Fascinating visual demonstration, great for classrooms and student use
Instructions and safety data sheet included
Description
This demonstration utilizes hydrogen peroxide as a means of illustrating the concept of Oxidation-Reduction reactions. It is first used to oxidize the iodide ion to iodine (red color), and then to reduce the much stronger Potassium permanganate ion to manganese and oxygen (colorless). Kit Includes: 1 x 100 ml Hydrogen Peroxide, 3% Solution 1 x 200 ml Potassium Iodide, 0.1M Solution 1 x 200 ml Potassium Permanganate, 0.02M Solution 1 x 10 ml Sulfuric Acid, Concentrated Equipment needed: 2 x 250ml Beaker (Eisco product number BK0107) 100ml Graduated cylinder (Eisco product number CH0353D) 2 droppers Magnetic Stirrer and Stir bar (optional) (product number MGST1V1)
