1. Neutralization Reactions
Despite heavy fire, McAllister’s aim
was true, and his carefully measured
hydrochloric acid found its mark in
the enemy’s reservoir of sodium hydroxide
McAllister grinned, one of the
enemy’s strongest bases had finally been neutralized

2. Neutralization: An Acid Base Rxn
Hydrochloric acid + sodium hydroxide ?
HCl + NaOH NaCl + HOH
Hydroxide ion
ACID + BASE SALT + WATER
Complete neutralization occurs when
The acid H+ and the base OH- are 1:1

3. Double Replacement Reaction
What kind of reaction?
Double Replacement Reaction

4. Neutralization Reactions
Phosphoric acid + ammonium hydroxide ?
H3PO4 + NH4OH  3HOH + (NH4)3PO4
Magnesium hydroxide + nitric acid  ?
Mg(OH)2 + 2HNO3  2HOH + Mg(NO3)2

5. Complete neutralization . . .
Occurs when H+ and OH- are in a 1:1 molar ratio
MaVa = MbVb
BE CAREFUL
If the H+ or OH- has a subscript you have to account for it in the formula. BECAUSE YOU NEED THE MOLARITY OF THE IONS....after ionization!
Ex. If you have 1L of HCl, what M of HCl is necessary to neutralize 1L of 1M Mg(OH)2?

6. Neutralization practice
55mL of an 8M HCl solution is completely neutralized by 26mL of Ca(OH)2
Write the balanced neutralization reaction.
What is the concentration of base that was used?
What is the net ionic equation?
What are the spectator ions?

7. Neutralization practice
Write the balanced neutralization reaction.
2HCl + Ca(OH)2  2HOH + CaCl2
What is the concentration of base that was used?
8.46M
What is the net ionic equation?
H+ + OH-  HOH
What are the spectator ions?
Ca2+ + Cl-
