Is it safe to touch elephant toothpaste?
Is it safe to touch elephant toothpaste?
The original elephant toothpaste reaction, which uses a much higher concentration of hydrogen peroxide, can cause both chemical burns and thermal burns. The kid's version uses chemicals that are safe for children to touch. The lower concentration of peroxide can still discolor fabrics.
What is the formula for elephant toothpaste?
What is Elephant Toothpaste? This large demonstration uses hydrogen peroxide (H2O2), sodium iodide (NaI) and soap. First we pour in the hydrogen peroxide, then the soap and finally the sodium iodide. The hydrogen peroxide used in the demonstration is 30% hydrogen peroxide.
Is Elephant toothpaste edible?
The usual Elephant's Toothpaste is soap and hydrogen peroxide, so no, not edible (strictly speaking). There are foaming agents that are edible.
How hot is elephant toothpaste?
The 500 ml of water has a heat capacity of around 2100 J/K. So, the solution gets about 12 K hotter.
Why is it called elephant toothpaste?
Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat! This experiment is sometimes called “Elephant's Toothpaste” because it looks like toothpaste coming out of a tube, but don't get the foam in your mouth!
Why is elephant toothpaste hot?
The foam you made in this classic Elephant's Toothpaste reaction is extra-special because each tiny foam bubble is filled with oxygen. Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat!
What is the conclusion of elephant toothpaste?
Our hypothesis stated that the trial using the 30% solution would be the fastest and it was proven correct. It was the fastest because it had more pure hydrogen peroxide making it have more oxygen when broken down and pushing the foam out faster.
Can you use potassium iodide tablets for elephant toothpaste?
You can add 5 grams of starch to the hydrogen peroxide. When the potassium iodide is added, the resulting foam will have light and dark patches from the reaction of some of the starch to form triiodide. You can use yeast instead of potassium iodide.
Is Elephant Toothpaste a solid liquid or gas?
The liquid hydrogen peroxide was being converted into liquid water and oxygen gas. Liquids and gases are two of the three phases of matter with solids being the third kind. Oxygen is a new substance formed in this chemical reaction and it has different properties than the original hydrogen peroxide.
What is the hypothesis for elephant toothpaste?
HYPOTHESIS. My hypothesis is that the reaction will have a greater production of bubbles when used with the 3 oz dish soap. This is my hypothesis because the dehydration of hydrogen peroxide produces oxygen, which makes the dish soap foam up.
What is elephant toothpaste used for?
Elephant's toothpaste is a foamy substance that's created when you combine water, hydrogen peroxide, yeast, and dish soap. It is commonly used in classrooms to demonstrate an exothermic reaction. More recently, it's been used at the 2019 Miss Virginia pageant and for gender reveals.
