Discover how ions are arranged in precipitation reactions and practise completing ionic equations using this lesson plan with activities for 14–16 year olds.

In this activity, students select diagrams that best represent the arrangement of ions before and after two solutions are mixed to form a precipitate. The diagrams focus thinking and discussion about precipitation reactions. They observe and interpret a practical demonstration and use ideas about particles to explain their observations.
