1. Predicting Single & Double Displacement Reactions

2. The Activity Series K Na Li Ca Mg Al Zn Fe Ni Sn Pb H Cu Hg Ag Au
The Activity Series is used to predict the outcome of single displacement reactions
The higher a metal is on the Activity Series, the more likely it will react with those below it
A metal will not displace a metal higher on the activity series than itself

3. The Activity Series Cont.
The metals near the top are more reactive because their valence electrons are more easily removed
H is the only nonmetal in the series, H2 may be displaced from acids or can be given off when a metal reacts with H2O producing H2 + metal hydroxide

4. The Activity Series QuestionsK Na Li Ca Mg Al Zn Fe Ni Sn Pb H Cu Hg Ag Au
The Activity Series Questions
Which of these will react?
K + NaCl  ???
K + NaCl  Na + KCl
Al + AgNO3  ???
Al + AgNO3  Ag + Al(NO3)3
Cu + CaCO3  ???
Cu + CaCO3  No rxn
Pb + ZnO  ???
Pb + ZnO  No Rxn

5. The Solubility Table
The Solubility Table is used to predict the outcome of double replacement reactions

6. The Solubility Table Cont.
If both products of a double replacement reaction are soluble then no reaction occurs
If at least one product of a double replacement reaction is solid then a reaction occurs
A double displacement reaction involves two ionic compounds that are dissolved in water

7. The Solubility Table Questions
Which of these will react?
NaCl (aq) + Ba3(PO4)2 (s)  ???
NaCl (aq) + Ba3(PO4)2 (s)  No Rxn
FeCO3 (s) + CaCl 2 (aq) ???
FeCO3 (s) + CaCl2 (aq)  FeCl2 (aq) + CaCO3 (s)
LiNO3 (aq) + MgBr2 (aq)  ???
LiNO3 (aq) + MgBr2 (aq)  No Rxn
Zn(OH)2 (s) + NiSO4 (aq)  ???
Zn(OH)2 (s) + NiSO4 (aq)  ZnSO4 (aq) + Ni(OH)2 (s)
