This Unilever Laboratory Experiment, published in 1970, describes the analysis of fluorescers from soap and soapless detergent powders. The procedure describes how the fluorescers can be extracted from the product, separated by thin layer chromatography techniques, and made visible by exposing the chromatograms to...

This Catalyst article investigates how honeycomb (cinder toffee) is made using a thermal decomposition reaction to produce the gas bubbles. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down...

Tunnelworks is a series of teaching and learning resources linking mathematics and science to the Thames Tideway Tunnel project, a major new sewer that will help protect the River Thames from increasing pollution. Background to the project is given in the...

This Catalyst article takes a look at the winners of the Nobel Prize for Chemistry 2012 who revealed how cells communicate.

All functions of the human body require signals to be released, detected by a receptor in the right place and an appropriate response to be mounted. For example, hormones can be...

Students test crystal (alum) deodorants using either a red cabbage indicator or a universal indicator. The universal indicator suggests that the deodorant reacts as an acid, whereas the red cabbage suggests that the deodorant reacts as a base. What is happening here?
