From palm oil to African black soap, discover how soap is made and how it cleans. This 21-slide interactive lesson on saponification takes pupils from first ideas to exam-style explanations, with 12 self-marking activities and nothing to prepare beforehand.
Pupils describe fats and oils as esters of glycerol and fatty acids, compare saturated fats with unsaturated oils and follow saponification with sodium hydroxide, including salting out. They link the process to traditional black soap made with plant ash, explain how soap lifts grease, and compare soaps with soapless detergents in hard water.
Supports the organic chemistry content of UK GCSE Chemistry (AQA, Edexcel and OCR) and the Nigerian Senior Secondary Chemistry curriculum (SS2–SS3), including WAEC and NECO exam preparation.
