Question 31
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.
Based on your observations, arrange the metals from the most reactive to the least reactive.
