In this lab, you will investigate the reactivity of four metals (Zinc, Aluminium, Copper, and Magnesium) with hydrochloric acid. You will record observations, write equations, and determine the reactivity order of these metals.
Total Marks: 30
Materials
Dilute hydrochloric acid (0.5M)
Samples of: Zinc, Aluminium, Copper, Magnesium
Test tubes and test tube rack

Procedure & Observations
Part 1: Metal-Acid Reactions (20 marks)
Instructions: For each metal, add a small piece to 2mL of hydrochloric acid in a test tube. Record your observations and complete the equations.
Magnesium + Hydrochloric Acid
Zinc + Hydrochloric Acid
Aluminium + Hydrochloric Acid
Copper + Hydrochloric Acid
Part 2: Reactivity Series (10 marks)
Based on your observations, arrange the metals in order of reactivity (most reactive first):
