Amaze a Science Class With Elephant Toothpaste: This experiment shows the decomposition of hydrogen peroxide catalyzed by potassium iodide. The reaction is done in a tall graduated cylinder so that the foamy product shoots out very quickly in a tall cylindrical shape; hence, the name elephant t. NCSU – Dept. of Chemistry – Lecture Demonstrations Kinetics Catalytic Decomposition of H 2O2 – Elephant’s Toothpaste Description: The iodide ion from KI or NaI is used as a catalyst to decompose. Students have to match cards to the type of particle they are, and the first to get four in a line wins. This looks like a great fun way to practice using these terms, and the activity could easily be adapted to other topics. The original files including an editable doc can be found in this Education in Chemistry article by Catherine Smith. Step-by-step in­struc­tions. Take a tray and a glass. Pour 50 ml of a 30% so­lu­tion of hy­dro­gen per­ox­ide into the glass, add a few drops of dish­wash­ing liq­uid and 2 g of food col­or­ing. Elephant's Toothpaste A great fun demonstration of the action of a catalyst and also of an exothermic reaction. In a measuring cylinder 100 vol hydrogen peroxide is mixed with some washing-up liquid or bubble bath and some food colouring.

Elephant toothpaste reaction Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide using potassium iodide or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. 26.11.2019 · How to Make Elephant Toothpaste. Making elephant toothpaste is an easy and fun science experiment that you can do with your kids at home or with students in the lab. It is the result of a chemical reaction that creates a. The original elephant toothpaste reaction, which uses a much higher concentration of hydrogen peroxide, can cause both chemical burns and thermal burns. While it produces a larger amount of foam, it's not safe for kids and should be performed only by an adult using proper safety gear.
