Competition for oxygen
This experiment involves the reaction of a metal with the oxide of another metal. When reactions like these occur, the two metals compete for the oxygen. The more reactive metal finishes up with the oxygen (as a metal oxide). If the more reactive metal starts as the oxide then no ...

Making nylon: the ‘nylon rope trick’
Perform this ‘trick’ with a solution of decanedioyl dichloride in cyclohexane floated on an aqueous solution of 1,6-diaminohexane. As nylon forms at the interface, it can be pulled out as fast as it is produced forming a long thread: the ‘nylon rope’.

The methane rocket
A strong plastic bottle is filled with a 2:1 ratio of oxygen to methane and the mixture ignited with the bottle standing on a suitable ‘launch pad’. The mixture ignites with a loud bang and the bottle flies several metres.

The effect of concentration on reaction rate
Sodium thiosulfate solution is reacted with acid – a sulfur precipitate forms. The time taken for a certain amount of sulfur to form can be used to indicate the rate of the reaction.

Testing for negative ions
This activity is in two parts; first, students make observations while carrying out tests for various negative ions, then they use their observations to help identify the negative ions present in a number of solutions.

Challenging Plants: Fertilisers - Practicals
Nutrients essential for plant growth are obtained naturally from soil or other growing media. However, supplies become depleted and fertilisers are needed to increase the availability of nutrients to plants. An understanding of chemical changes is used to making fertilisers, often designed to meet specific requirements such as particular nutrient ...

Molecules against malaria
This medicinal chemistry case study is designed to introduce students to the development of antimalarial 4-aminoquinolines and the early stages of drug discovery and development. It focuses on antimalarial 4-aminoquinolines (4-AQs) and involves an introduction to malaria, its causes, societal impact and the need for new drugs. It then presents ...
