Chemistry Form 4 Experiment 5.1 Info

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.

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

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. It was a Thursday afternoon, and the Form

“Magnesium!” the class shouted.

“Last one,” Ravi whispered, holding the magnesium ribbon with a pair of tongs. Puan Aishah wandered over. “Careful, Ravi. This one is dramatic.” Maya stood up, her voice steady
