Chemistry in your cupboard: Harpic


Link the post-16 topics of group bonding, acid rain, equilibria and Le Chateliers principle and strong and weak acids to the topic of removing limescale. Learn about a range of real life contexts for these chemical ideas through written material, and questions to encourage learning and test understanding. Use this material for enrichment towards the end of a post-16 course, or to add interest and context to your teaching.

The Chemistry in your cupboard resource series describes the chemistry that underlies nine well-known, household products. Each section explores the chemistry of these products and covers a wide range of chemical principles and topics.
