The Reactivity Series of metals

Students use this simulation to investigate the differences between potassium, sodium, iron and gold in reactivity with water in the construction of a bridge. Teachers have to explain how the reactivity series of metals can be determined by considering their reaction with oxygen, water and acid, and how to use the reactivity ...
