Core &
Ext. Metals: Displacement Rxns & Stability of Compounds
Slide 21 of 42
Displacement
Reaction: Examples
In a displacement reaction, a more
reactive metal will displace a less reactive metal from a
solution.
What will
happen if a piece of copper is placed in a beaker of calcium chloride
solution?
®
chloride
+
copper
Calcium
No reaction
Copper challenges
calcium
for the chloride
ions
…and the challenge
fails
The challenge fails because copper is below
calcium in the reactivity series.
It’s like Kenny trying to displace Stan from
Piggy’s sty—that’s not going to happen!
