Elephant Toothpaste Pdf Chemistry Chemical Substances Elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide when mixed with a catalyst like potassium iodide or yeast and warm water. the study demonstrates this reaction using a safe version for children with hydrogen peroxide and a yeast catalyst. Ed reaction: elephant toothpaste overview this quick demonstration showing the decomposition of hydrogen peroxide, catalyzed by iodide ions, provides students wi. h visual evidence of a chemical reaction. students compare the reaction rate of the catalyzed and uncatalyzed reactions and use their data to sketch an ener.
Elephant Toothpaste Pdf Lesson 33 Elephant Toothpaste Estimated Time Lab #3: elephant toothpaste scientific concept: to investigate one of the types of reactions. purpose: this activity is a type of dissociation reaction, in which hydrogen peroxide is broken down into oxygen and water, with the use of a catalyst. background information: you might remember mom treating your scraped knee or a cut with hydrogen. This document describes a project to perform an elephant toothpaste experiment for students at the ferrini school. the experiment involves mixing hydrogen peroxide, liquid soap, and potassium iodide, which generates oxygen bubbles and foam.
