Neutralization Reaction

2. A. Neutralization Reaction
Chemical reaction between an acid and a base.
Products are a salt (ionic compound) and water.

3. A. Neutralization Reaction
ACID + BASE  SALT + WATER
HCl + NaOH  NaCl + H2O =
Neutralization does not always mean pH = 7.

4. A. Neutralization Reaction
KOH + HNO3  H2O + KNO3
Acid?
Base?
Salt?
HNO3
KOH
KNO3

5. Writing neutralization equations
When acids and bases are mixed, a salt forms
NaOH + HCl  H2O + NaCl
base + acid  water + salt
Ca(OH)2 + H2SO4  2H2O + CaSO4
base acid water salt

6. Step 1: write out the reactants LiOH(aq) + H2CO3(aq) 
Question: Write the chemical reaction when lithium hydroxide is mixed with carbonic acid.
Step 1: write out the reactants
LiOH(aq) + H2CO3(aq) 
Step 2: determine products … H2O and Li+(CO3)2-
LiOH(aq) + H2CO3(aq)  Li2CO3(aq) + H2O(l)
Step 3: balance the equation
2LiOH(aq) + H2CO3(aq)  Li2CO3(aq) + 2H2O(l)

7. Write balanced chemical equations for these neutralization reactions.

KOH(aq) + HClO2(aq)

8. SOLUTIONS a) 3Fe(OH)2 (aq) + 2H3PO4 (aq)  Fe3(PO4)2 (aq) + 6H2O (l)
b) Ba(OH)2 (aq) + 2HCl (aq)  BaCl2 (aq) + 2H2O (l)
c) Ca(OH)2 (aq) + 2HNO3 (aq)  Ca(NO3)2 (aq) + 2H2O (l)
2Al(OH)3 (aq) + 3H2SO4 (aq)  Al2(SO4)3 (aq) + 6H2O (l)

9. SOLUTIONS
e) 2NH4OH (aq) + H2S (aq)  (NH4)2S (aq) + 2H2O (l) f) KOH (aq) + HClO2 (aq)  KClO2 (aq) + H2O (l)
