Caption: Catalysed hydrogen peroxide decomposition. Animation of molecules of the inorganic chemical hydrogen peroxide (red and white) and its decomposition reaction being catalysed by iodide ions (I-, purple). Atoms are represented as coloured spheres joined by molecular bonds. Hydrogen peroxide (H2O2) consists of two atoms of oxygen (red) and two atoms of hydrogen (white). The animation shows two molecules of hydrogen peroxide colliding with an iodide ion, and bonds breaking and forming. The products are two water molecules (H2O) and an iodide-oxygen complex. The latter breaks apart as an oxygen molecule forms (O2), leaving the iodide ion unchanged. The iodide is not used up, and acts as a catalyst and increases the reaction rate which is slow at room temperature. Hydrogen peroxide is a powerful oxidizer, used as a bleach and as a reagent in the chemical industry.
