Topic: The reactivity series
Problem: Which of the following metals are more reactive with acids – magnesium, zinc, aluminum, iron, lead, and copper?
Hypothesis: Aluminum is the most reactive with acids because it occurs in group III.
Aim: To perform a comparative test on which metal is the most reactive with acids.
Experiment: A comparative test is done using time to find which metal has the fastest reaction
Skill: P & D
Apparatus : Equipment: 1. 6 beakers
2. Water
3. Measuring cylinder
4. Watch or Clock
Materials: 1. Aluminum foil
