Saponification Practical - Make your own soap

This is a chemistry practical for KS4 science students and A-level chemistry students that lets them make their own soap via a saponification reaction between vegetable fats and sodium hydroxide from lye. It also explains the saponification reaction in detail and how soaps work. It can even help students to understand the importance of chemistry in industry as the saponification reaction is still widely used to make bar soaps on large scale.
