Product Details

Eerie and incredibly cool! Mix colorless and orange solutions in a beaker and start stirring. The color of the solution changes from orange to green. Dim the lights, switch on a black light and the real show begins! Observe the brilliant, fluorescent orange glow! This unique adaptation of a classic oscillating reaction is due to rising and falling concentrations of ruthenium(II) and (III) complex ions. Use the beautiful, radiant color changes to illustrate oxidation states, but then sit back and enjoy the show! Includes Teacher Demonstration Notes, a reproducible student worksheet, and answer key. Enough materials are included to perform the demonstration seven times. Concepts: Oscillating reactions, oxidation–reduction reactions, reaction mechanisms, kinetics, catalysts. Time Required: 20 minutes Materials Provided: Cerium ammonium nitrate and ruthenium chloride acidified solution, malonic acid, potassium bromate, and sulfuric acid solution. Note: A UV lamp or other black light source is required and available separately.
