The experiment was simple, yet dangerous to a careless hand. Procedure 5.1: Investigate the reaction of metals with the salt solution of another metal.
“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
“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 experiment was simple, yet dangerous to a careless hand
He dropped the ribbon into the final bath of blue. The experiment was simple
In their lab books, under , Maya wrote the final line of the story:
