Experiment
Allotropes of sulfur

In association with Nuffield Foundation

Observe the changes in colour and consistency of sulfur as you heat it, melt it and eventually boil it.
Experiment
Reactions of chlorine, bromine and iodine with aluminium

In association with Nuffield Foundation

Produce some spectacular exothermic redox reactions by reacting aluminium with halogens.
Experiment
Halogens in aqueous solution and their displacement reactions

In association with Nuffield Foundation

Explore the chemical properties of halogens using this demonstration or class experiment. Includes kit list and safety instructions.
Experiment
The position of iron in the reactivity series

In association with Nuffield Foundation

This experiment shows the position of iron in the reactivity series, by heating iron metal with the oxides of two other metals, copper and magnesium.
Experiment
Preparing salts by neutralisation of oxides and carbonates

In association with Nuffield Foundation

Try these class experiments to illustrate the production of soluble salts from insoluble metal oxides and carbonates. Includes kit list and safety instructions.
Experiment
Reacting magnesium with copper(II) oxide

In association with Nuffield Foundation

Illustrate reduction, oxidation and the relative reactivity of magnesium and copper(II) oxide in this demonstration. Includes kit list and safety instructions.
Experiment
Liquefying chlorine gas

In association with Nuffield Foundation

Liquefy gaseous chlorine by passing it over a ‘cold finger’ condenser using a dry ice/ethanol mixture and compare it with bromine and iodine in their condensed state as part of a study of the trends in the physical properties of the halogens.
Experiment
Extracting iodine from seaweed

In association with Nuffield Foundation

Discover how ribbon seaweed (or kelp) can be used as a source of iodine in this demonstration or class experiment. Includes kit list and safety instructions.
Experiment
Where does carbon come in the reactivity series?

In association with Nuffield Foundation

The position of carbon in the reactivity series is determined by heating carbon with metal oxides and looking for evidence of a reaction.
