  Experiment

  The equilibrium between two coloured cobalt species

  In association with Nuffield Foundation

  In this demonstration the equilibrium between two different coloured cobalt species is disturbed. Le Chatelier’s principle is used to predict a colour change.

  Experiment

  Money to burn

  In association with Nuffield Foundation

  Surprise your students by soaking a piece of paper (or an old £5 or £10 note) in a mixture of ethanol and water and igniting it. Watch as the ethanol burns… but the paper does not.

  Experiment

  Exploding bubbles of hydrogen and oxygen

  In association with Nuffield Foundation

  Produce a small explosion in your classroom by electrolysing water then re-combining the hydrogen and oxygen gas.

• 
  Experiment

  Chemiluminescence of luminol: a cold light experiment

  In association with Nuffield Foundation

  Show how the energy of a chemical reaction can be given out as light by revealing how a solution of sodium chlorate(I) oxidises an aqueous solution of luminol (3-aminophthalhydrazide) to produce a blue chemiluminescent glow – without any increase in temperature.

  Experiment

  Heating Group 1 metals in air and in chlorine

  In association with Nuffield Foundation

  This is a demonstration that shows the reactions of Group 1 metals in air and in chlorine.  It does not clearly show the trends in reactivity of Group 1 metals, which are better demonstrated by the reactions in water, which follow on well from this demonstration.

  Experiment

  Ammonia fountain demonstration

  In association with Nuffield Foundation

  Try this experiment to make a miniature chemical fountain using only soluble ammonia and atmospheric pressure. Includes kit list and safety instructions.

• 
  Experiment

  Determining relative molecular masses by weighing gases

  In association with Nuffield Foundation

  Demonstrate how different gases can be weighed in a gas syringe and their relative molecular masses determined using the ideal gas equation.

• 
  Experiment

  Electrolysis of molten zinc chloride

  In association with Nuffield Foundation
