2. Neutralization the driving forces are:
ACIDS, BASES and SALTS
Neutralization the driving forces are:
formation of water & heat
Acid + Base 
Salt + Water
H+ + OH- 
H2O

3. How do we recognize a salt?
ACIDS, BASES and SALTS
How do we recognize a salt?
metal + halogen (group 17)
metal + polyatomic ion (Table E)

4. ACIDS, BASES and SALTS

9. acidic, basic or neutral on the pH scale?
ACIDS, BASES and SALTS
Neutralization
Acid + Base 
Salt + Water
What is the pH of the salt formed ?
acidic, basic or neutral on the pH scale?

10. Strong Acid + Strong Base 
neutral pH salt solution (~7)
Strong Acid + Weak Base 
acidic pH salt solution (<7)
Weak Acid + Strong Base 
basic pH salt solution (>7)
Weak Acid + Weak Base 
??? need more information to figure out

11. Salt + Water  Acid + Base
Hydrolysis –
reverse of the neutralization reaction
Salt + Water  Acid + Base
Ca(NO3)2 + H2O  HNO3 + Ca(OH)2

12. CuCl + H2O 
Na2CO3 + H2O 
