    What makes it go?

    Carry out certain experiments in a given order. Then without doing any calculations, explain what the driving force of the reaction is in each case – ie qualitatively rather than quantitatively.

    Chemiluminescence of luminol: a cold light experiment

    In association with

    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.

    The sublimation of air freshener

    In association with

    Sublimation is an interesting physical change. When a substance sublimes, it changes directly from a solid to a gas without passing through the liquid state. Dry ice sublimes, as do iodine and mothballs. This experiment involves the study of another common substance that sublimes – air freshener.
