1. 5.4 Neutralization Reactions

2. What if we took an acid and base, and reacted them together?

3. Neutralization
A double displacement reaction between an acid and a base.
The products always include water and an ionic compound (sometimes referred to as a salt).
Our acid and base properties are “neutralized”, and our pH is brought closer to our neutral value of 7

4. Neutralizing with a hydroxide compound
HCl(aq) + NaOH(aq) 
H2O (l) + NaCl (aq)
H+ & Cl Na+ & OH-

5. Neutralizing with a carbonate compound
When using a carbonate compound, the general reaction will yield our same products, but also carbon dioxide
H2SO4(aq) + CaCO3(aq)  Sulfuric acid calcium carbonate
H2CO3(aq) + CaSO4(s)
H2O(l) + CO2(g)
Carbonic acid (H2CO3 ) immediately decomposes into water and carbon dioxide. 

6. Sodium Bicarbonate NaHCO3
Can either Donate or Accept a H+ ion therefore it can neutralize both acids and bases
Loses the Na+ and forms a bicarbonate ion

7. Write out the chemical equation and balance it.
1. A sample of aqueous hydrogen sulfate is added to a solution of aqueous ammonium hydroxide
2. A sample of aqueous sulphuric acid is added to a solution of aqueous sodium bicarbonate.

8. Once a battery has been discarded, we can clean and reuse the battery acid or neutralize it.
