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.
“Look!” Lin gasped. “The blue is disappearing! And… is that copper metal?” chemistry form 4 experiment 5.1
“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. The more reactive metal (magnesium or zinc) acts
Lin nodded, swirling the last of the pale, colourless solution down the sink. “That’s not war,” she smiled. “That’s displacement. And now we know how to prove who belongs where.” ” Maya whispered
He dropped the ribbon into the final bath of blue.
