Caption

Rapid redox reaction. Footage of a demonstration of a rapid redox reaction, with crystals of potassium permanganate added to a reaction flask containing hydrogen peroxide solution (35 percent). This reaction produces high concentrations of oxygen gas and water vapour which are expelled from the reaction flask at a rapid rate. In this reaction, permanganate ions reduce to manganese ions when they gain electrons from hydrogen peroxide molecules which lose electrons and oxidise, forming oxygen gas and protons.
