1. Displacement Reactions

2. Which metal here is the most reactive?
How do you know?
Put the metals in order from most to least reactive?

3. The Reactivity Series of Metals
Some metals are more reactive than others.
The reactivity series is a list of metals IN ORDER from the most to the least reactive,

4. What is a Displacement Reaction?
“Displace” means to “SHIFT”
In a displacement reaction a MORE reactive metal will SHIFT a LESS reactive metal from a solution and take its place.
Example: Copper and Silver Nitrate
Which is the most reactive metal, Cu or Ag?

5. Copper and Silver Nitrate Reaction
Copper is MORE reactive than silver so it will SHIFT the silver out of the compound and take it’s place.
Word Equation
Copper + Silver Nitrate Copper Nitrate + Silver
Symbol Equation
Cu + AgNO Cu(NO3)2 + Ag
Balanced Symbol Equation
Cu + 2AgNO Cu(NO3) Ag

6. A Spectator Ion
In the reaction above, the nitrate ion is present as a reactant and a product but DOES NOT take part in the reaction. It is called a spectator ion.

7. Your turn to predict if a reaction will occur
Magnesium and Lead Nitrate?
Zinc and Lead Nitrate?
YES to both
What is the spectator ion in each reaction?
The nitrate ion

8. What about Copper and Lead Nitrate?
This reaction won’t happen because copper is below lead on the reactivity series.
