Elephant Toothpaste Lab Report

1. Title: Amount of Elephant Toothpaste Created With Different Amounts of Hydrogen Peroxide.

Important: H.P. = Hydrogen Peroxide; P.I. = Potassium Iodide

2. Introduction - The Question: How does adding more or less hydrogen peroxide to potassium iodide and dish soap affect the amount of foam produced?

The world of chemical reactions is none less than an absolutely fascinating one. There are many experiments or tests you can perform to explore this intriguing topic. A chemical reaction is when one or two (or more) substances react and combine into a different substance, and one of these chemical reactions is commonly known as “Elephant Toothpaste.” Elephant toothpaste is a foam created by pouring Potassium Iodide into a mixture

Procedures:
First, we put on gloves to ensure safety.
We set down a tray on a table, and we set down all our Materials listed above.
We put different amounts of hydrogen peroxide in a graduated cylinder (5, 10, 15, 20 ,25) ml.
We add food dye/ food coloring and dish soap into the hydrogen peroxide.
We mix the mixture inside the graduated cylinder.
One person poured 0.6ml of potassium iodide into the mixture as another person quickly stirred the mixture.
We wait until the mixture foams to its peak, then we record the volume of the mixture.
We wash our tools and repeat the process 3 times to ensure that our results are accurate.

6. Observations:

During our lab, we noticed many interesting things that we took note of.
The foam created by mixing the H.P. and the P.I was hot when it first foamed up.
The foam started to sink after it reached its peak height
If we used more than 25 m.l. of H.P. in our trials, it would be hard to measure the amount of foam produced since the foam spilled over the 1000ml line in the graduated cylinder.
When we added more H.P. the foam rised
