"Elephant Toothpaste" With Potassium Permanganate and Hydrogen Peroxide: It is a experiment similar to Experiment #2, decomposition of Hydrogen peroxide generate Oxygen, which turns detergent into foam. Now, it's time for the titration. 3. Why could we use the end point to calculate the starting concentration of hydrogen peroxide? In a titration experiment, a known concentration of one chemical in a reaction is used to find the concentration of the other. ; A dilute (10 mg/l) of potassium permanganate can be used to eliminate snails from plants prior to placing them in a fresh-water aquarium. Even though it made the reaction go faster, the substance itself didn’t change during the reaction. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide using potassium iodide or yeast and warm water as a catalyst. In this use, it was called Z-Stoff.This propellant is still used in torpedoes. 18. Have you ever heard about a viral experiment called Elephant Toothpaste? To learn more, visit our Earning Credit Page. As the peroxide breaks down, it releases a lot of oxygen. Open the stopcock to let the bubbles through, then remove the beaker. • This reaction can also be used as a qualitative test for the different types of alcohols because there is a distinct colour change. A student followed the procedure of this experiment to determine the percent NaOCl in a commercial bleaching solution that was found in the basement of an abandoned house. 4. Dissolved potassium permanganate Solutions of KMnO 4 have been used together with 80% hydrogen peroxide to propel a rocket. These mixtures possess varying amounts of hydrogen peroxide and potassium iodide. Perform experiment #1 first. In a titration experiment, a known concentration of one chemical in a reaction is used to find the concentration of the other. 19. Potassium permanganate is very fast reacting (on the order of seconds) with hydrogen sulfide and organic odor compounds, making it a good choice for application in solids processing where retention times may be very short. Since every two moles of potassium permanganate uses five moles of hydrogen peroxide, we can use stoichiometry to find out the moles of hydrogen peroxide present in the solution. To find the concentration of hydrogen peroxide, dividing the starting volume (1mL) by 1000 to get the volume in liters. Add 20mL of water to the flask and swirl gently. Hydrogen peroxide is corrosive and harmful to your health. A glowing splint … 11. imaginable degree, area of hydrogen peroxide, 3% (50 mL) potassium permanganate solution, 0.1 M (~150 mL) sulfuric acid, 0.1 M (~250 mL) distilled or deionized water; All of the specialty lab equipment and chemicals needed for this and other lab sessions are available individually from Maker Shed or other laboratory supplies vendors. If no, then great – you might find it interesting to learn how to do it. Slowly add one drop of potassium permanganate to the flask at a time. So, if we know the amount of moles in the potassium permanganate we used, we can also know the number of moles of hydrogen peroxide present. Safety Tip!! 15. 5. Envir.
