This visual demonstration allows students to watch the effects of electrons moving from an oxidizing compound to a reducing compound. -- The transfer of electrons changes the properties of the compounds, creating a color change that is easily observed. When the procedure is completed, students are expected to write the complete equations for these reactions and explain the flow of electrons between the reactants. -- Includes: Ferrous ammonium sulfate, Glucose, Hydrogen peroxide 3%, Methylene blue 1% solution, Potassium hydroxide 0.5M solution, Potassium permanganate 0.05M solution, Potassium thiocyanate solution, Sulfuric acid 6.0M solution, Tin (II) chloride solution, and instructions. |
