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

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.” chemistry form 4 experiment 5.1

Lin dropped a small piece of copper wire into the blue liquid. They waited. One minute. Two. The copper sat at the bottom like a sleeping snake. The blue remained blue. “Correct

“Today,” she had announced, her voice crackling through the lab’s humid air, “you are all forensic chemists. A factory has spilled three different metals—magnesium, zinc, and copper—into a vat of copper(II) sulphate solution. Your job is to determine which metal is the ‘hero’ that reacts, and which are the ‘villains’ that remain inert.” “That’s displacement
