Chemistry Form 4 Experiment 5.1 -

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.

“Exothermic,” Maya whispered, recording the temperature rise. The magnesium was even more reactive than zinc. It had ripped the copper from the solution with such force that it generated heat. chemistry form 4 experiment 5.1

Only the blue solution. Nothing happened. It remained still, a calm witness. The more reactive metal (magnesium or zinc) acts

“No reaction,” Maya noted, scribbling in her book. “Copper + copper sulphate → no change. That means copper is low in the reactivity series. It can’t kick itself out of its own salt.” The magnesium was even more reactive than zinc

It was a Thursday afternoon, and the Form 4 Science lab smelled of antiseptic and old wood. Maya, Lin, and Ravi huddled over their workstation, a neat row of four test tubes clamped to a metal stand. Their teacher, Puan Aishah, had given them a puzzle.

“Correct. And the reactivity series order from this experiment?”
