What makes hydrogen peroxide explode in this elephant’s toothpaste experiment? Museum Educator Jeannine explains how potassium iodine acts as a catalyst to cause hydrogen peroxide to break down faster into water and oxygen gas in an exothermic reaction, producing heat, as well as a foamy explosion thanks to the addition of soap! #Chemistry #STEMEducation #ScienceExperiment #Science #WomenInSTEM | Museum of Science, Boston

The iodine clock reaction is a classic chemical clock demonstration experiment aimed at displaying chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886[1],[2]. The iodine clock reaction exists in several variations, each involving iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch. Two colorless solutions are mixed and, at first, there is no visible reaction. After a short time, the liquid suddenly changes to a dark blu

The iodine clock experiment is a classic chemistry demonstration used to show reaction rates!It involves mixing two clear solutions that, after a specific time delay, suddenly turn dark blue. This color change happens when iodine reacts with starch in the solution.The timing of the change can be controlled by adjusting concentrations or temperature, making it a great way to explore reaction kinetics and the effects of different variables on chemical reactions. #reels #explore #science | Explaini
