The method of preparation of a sulphonate paste described in this Unilever Laboratory Experiment is basically the same as that used by Unilever in the large-scale production of soapless detergents at the time of publication in 1964. The required reactants included an alkylbenzene hydrocarbon supplied by the...

This Unilever Laboratory Experiment, published in 1969, gives the procedure for using corrosion (ferroxyl) indicator to demonstrate anodic and cathodic areas on the surface of steel as it corrodes.

As in the previous editions, students of the Fourth Edition of Nuffield Advanced Chemistry were required to undertake a four-week study of an applied aspect of science which was based on chemical principles. The main purpose of this section of the course was to help students to see something of the scope of a...

This Problem Solving with Industry module was devised by the Centre for Science Education in collaboration with ICI. In this module students find out why pipes in a soda-ash chemical plant have become blocked with a white sludge. They identify the sludge and determine...

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...

Produced by The Centre for Industry Education Collaboration (CIEC), the activities in this resource allow students to examine science concepts applicable to the healthcare industries and the work of people in the sector.

The activities in the resources cover areas that include:
* Determination of the...

The We Are Aliens! teaching resources were produced to support the planetarium show made by NSC Creative. They have been produced by lead educators from the National Space Academy to use the context of space to teach physics, chemistry and biology in the curriculum. The resources contain practical activities,...

In this demonstration of a displacement reaction, a piece of foil in the shape of a Christmas tree is placed in lead nitrate solution. Within a few minutes the tree becomes covered with sparkling crystals of lead.

These ten videos from the Institution of Chemical Engineers, have been produced to provide fun and exciting demonstrations that are relevant to the Key Stage Four curriculum. The videos show the demonstration performed in front of a class, and show the reaction of the students to the demo.
