Try this microscale practical to explore the chemical changes in displacement, redox and precipitation reactions. Includes kit list and safety instructions.

In this visually engaging series of experiments, students observe and identify the chemical changes that take place in a range of reactions on a microscale. The practical features displacement, redox and precipitation reactions between various salts, including potassium manganate(VII), barium nitrate and ammonium vanadate(V).
