What is the result of elephant toothpaste?

The sodium iodide reacts with the hydrogen peroxide (H2O2) by removing an oxygen atom. This essentially produces water and oxygen gas (H2O + O2). The oxygen gas produced gets trapped in the soap which produces the big ball of foam. The reaction produces oxygen gas, water and iodine.

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.

What happens with elephant toothpaste?

The resulting foam (“elephant’s toothpaste”) demonstrates a chemical reaction that can “explode” in student engagement! Background Information: … The foam is oxygen-filled bubbles that result from the hydrogen peroxide being broken down into water (H2O) and oxygen (O2). This reaction uses yeast as a catalyst.

What is the purpose of elephant toothpaste?

How elephant’s toothpaste is used. 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.

What is elephant toothpaste and how does it work?

Hydrogen peroxide is unstable and breaks down over time into water and oxygen gas, but the catalyst potassium iodide speeds up that decomposition into a matter of seconds. Add some soap (and food coloring if you’re feeling adventurous) and you’ve got a mix of soapy water and gas to fill some bubbles.

Is Elephant toothpaste safe to touch?

It is safe to touch because all that foam is just soap, water and oxygen. Let your kids have some fun with the foam too. Just be sure to have a towel handy!

How do you do the elephant toothpaste experiment?

Procedure

  1. Measure 1/2 cup of hydrogen peroxide, and carefully pour it into the bottle.
  2. Add a big squirt of dish soap into the bottle, and swirl gently to mix.
  3. If you want to make your foam a single color, add a few drops of food coloring directly into the hydrogen peroxide, and swirl the bottle gently to mix.

Is Elephant toothpaste hot or cold?

The 500 ml of water has a heat capacity of around 2100 J/K. So, the solution gets about 12 K hotter.

What is Devil’s toothpaste?

He also, inadvertently, create a new mixture that is much stronger and more explosive than traditional elephant’s toothpaste which he dubbed devil’s toothpaste. The resulting explosion of food coloring and foam is more impressive than any special effect from a Hollywood movie.

Does elephant toothpaste get hot?

The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water and oxygen. The bottle felt warm to the touch because this was an exothermic reaction in which energy is given off in the form of heat.

What are the ingredients for 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.
  • 3 Tablespoons of warm water.
  • Liquid dishwashing soap.
  • Food coloring.
  • Small cup.
  • Safety goggles.

What is a good hypothesis for elephant toothpaste?

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.

Is Elephant Toothpaste a solid liquid or gas?

The soap molecules surround the oxygen gas bubbles in this way and stablize them so that they last for a longer time – as a “foam”. As the oxygen is continually made the foam squeezes out of the bottle like toothpaste…for an elephant! Foam is a kind of a mixture called a colloid – gas bubbles in a liquid.

How can I make elephant toothpaste faster?

The foam you made in this classic Elephant’s Toothpaste reaction is extra-special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst; a catalyst is used to speed up a reaction. It quickly broke apart the oxygen from the hydrogen peroxide.

What catalyst is used in elephant 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). When hydrogen peroxide (H2O2) decomposes, it breaks down to form water (H2O) and oxygen (O2).

How do you make elephant toothpaste with Coke?

Coca-Cola bottle, one ½ cup of 6% or 20-volume hydrogen peroxide (purchased from a beauty supply store), 5 squirts of dawn dish soap, blue and red food coloring, 1 teaspoon of active yeast dissolved in 2 tablespoons of warm water, one funnel, and a tray and towels to catch the overflowing toothpaste.
