Can I use potassium iodide for elephant toothpaste?
Elephant Toothpaste Procedure Squirt in a little dishwashing detergent and swirl it around. You can place 5-10 drops of food coloring along the wall of the cylinder to make the foam resemble striped toothpaste. Add ~10 mL of potassium iodide solution.
What makes elephant toothpaste explode?
Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container.
Is potassium iodide a catalyst for hydrogen peroxide?
Potassium iodide — a salt of iodine, and the dietary supplement that’s used to add iodine to table salt — provides that catalyst. “In the presence of potassium iodide, hydrogen peroxide decomposes almost immediately,” Hostetler said.
Does potassium iodide react with hydrogen peroxide?
The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and water vapor are trapped in soap bubbles resulting in a long, soapy snake.
What happens when you mix potassium iodide and hydrogen peroxide?
It’s made up of two hydrogen and two oxygen molecules. The potassium iodide is added, and the iodide ion that’s part of that compound attracts the oxygen in the hydrogen peroxide, breaking the bonds and rapidly transforming the hydrogen peroxide into water and oxygen gas.
Do you need yeast to make elephant toothpaste?
What You’ll Need: A clean 16-oz plastic soda bottle. 1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution; you can get this from a beauty supply store or hair salon) 1 Tablespoon (one packet) of dry yeast.
What is the best catalyst for elephant’s toothpaste?
The secret ingredient is actually sodium iodide, which acts as a catalyst (something that speeds up a chemical reaction, and in this case, it’s the decomposition of hydrogen peroxide).
What is the best container for elephant toothpaste?
A container ― any bottle with a narrow neck will show off the elephant toothpaste reaction to its best advantage. A pan to catch your results, though a bathtub would be a smart place to do this experiment.
What are the results of elephant toothpaste?
The original elephant toothpaste reaction, which uses a much higher concentration of hydrogen peroxide, can cause both chemical burns and physical burns . The light version uses chemicals that are safe for children to touch. Nevertheless, the lower concentration of peroxide can till discolor fabrics.
What is the formula for elephant toothpaste?
The activity is called ’Elephant’s Toothpaste’ because the large stream of foam looks like toothpaste that is big enough for an elephant! Hydrogen peroxide is a molecule made up of hydrogen atoms and oxygen atoms. It can be expressed using the chemical formula, 2H 2O 2.
What materials are used in elephant toothpaste?
Materials in the Elephant Toothpaste Experiment Hydrogen Peroxide (118 mL or 4 US fl Oz) Liquid Dish Soap (59 mL or 2 Us fl Oz, and 89 mL or 3 US fl Oz) Active Yeast (Packets of 1/4 Oz or 7g) Food Coloring Warm Water (20 mL or 0.70 US fl Oz) 2 Water Bottles with same shape (591 mL or 20 US fl Oz) 2 Measuring cups 2 Funnels
How can you make elephant toothpaste?
Make Elephant Toothpaste Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. In a separate container, mix a packet of active yeast with a little warm water. When you are ready to do the demo, pour the yeast mixture into the bottle.
