These experiments are from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry.
Class experimentElectrolysis of brine
Use this colourful practical to introduce students to the electrolysis of brine, or sodium chloride solution. Includes kit list and safety instructions.
DemonstrationThe equilibrium between two coloured cobalt species
In this demonstration the equilibrium between two different coloured cobalt species is disturbed. Le Chatelier’s principle is used to predict a colour change.
DemonstrationTurning copper coins into ‘silver’ and ‘gold’
Perform what looks like alchemy with ordinary copper coins in this teacher demonstration. Includes kit list and safety instructions.
Class experimentExtracting iron from breakfast cereal
Try this class practical or demonstration to extract food-grade iron from breakfast cereals using neodymium magnets. Includes kit list and safety instructions.
Class experimentEnergy content in foods
Try this class experiment to investigate how much energy different foods contain. Includes kit list and safety instructions.
Class experimentDetecting starch in food on a microscale
Test different foodstuffs for the presence of starch using iodine in this microscale class practical. Includes kit list and safety instructions.
Class experimentUsing indigestion tablets to neutralise an acid | 14-18 years
Investigate and measure the neutralising effect of indigestion tablets (antacids) on hydrochloric acid in this class practical. Includes kit list and safety instructions.
Class experimentAcid or alkali? Acidic or alkaline? A litmus paper test
Test a variety of substances to see if they are acidic or alkaline, using litmus paper as the indicator. Includes kit list and safety instructions.
Class experimentSeparating sand and salt by filtering and evaporation
Try this class experiment to practise manipulating mixtures of soluble and insoluble materials by separating sand and salt. Includes kit list and safety instructions.
DemonstrationExploding bubbles of hydrogen and oxygen
Create a small explosion in this demonstration by electrolysing water to produce hydrogen and oxygen bubbles. Includes kit list, video and safety instructions.
