“Magnesium!” the class shouted.
The more reactive metal (magnesium or zinc) acts as the displacer, while the less reactive metal (copper) is displaced. The reactivity series is not just a list—it is a hierarchy of chemical power. chemistry form 4 experiment 5.1
The solution turned from vibrant blue to a pale, cloudy colourless. The reddish-brown solid was pure, elemental copper. Zinc was the hero. “Magnesium
Maya stood up, her voice steady. “Magnesium is the most reactive, then zinc, then copper. Because a more reactive metal will displace a less reactive metal from its salt solution.” chemistry form 4 experiment 5.1
