Caption

Potassium permanganate reacting with glycerine. Time-lapse footage of the reaction between potassium permanganate (KMnO4, solid in dish) and glycerine (C3H5[OH]3, liquid added from syringe). This is a vigorous exothermic reaction, producing a loud crackling noise, heat and flames. The products are potassium carbonate (K2CO3), manganese (III) oxide (Mn2O3), carbon dioxide (CO2) and water (H2O). This is an example of a redox reaction. The potassium permanganate is the oxidizing agent and is reduced. The glycerine is the reducing agent and is oxidized.
