Question 32
Work in groups of five. Investigate the reactivity of metals with dilute acids using household items (Figure 6.15). The items are vinegar, lemon juice, aluminium foil, a steel paper clip and copper wire.
Caution: Vinegar is dilute ethanoic acid and lemon juice contains citric acid. They are safe to handle but may cause skin or eye irritation when in contact. Wear safety goggles and hand gloves. Handle the metals safely. Be careful of sharp edges.
Present your results to the class in the form of a role-play. Discuss with your group how to act out the reactions of each metal with the acids (vinegar and lemon juice).
