2. ACID + BASE  SALT + WATER
Neutralization Reactions (REVIEW)
Neutralization – chemical reaction between an acid and a base.
HCl + NaOH  NaCl + HOH
H2O =
ACID + BASE  SALT + WATER

3. A. Titration Titration Standard Solution
adding a known conc. to a solution to find an unknown conc.
Standard Solution
solution of known conc.

4. A. Titration
Equivalence Point
moles of H+ = moles of OH–

5. A. Titration

6. A. Titration

8. Acid/Base Indicators

9. MAVA = MBVB B. Calculations Example (find conc.)
A 25.0 mL solution of HCl was completely neutralized by 40.0 mL of
standard M NaOH.
What is the concentration of the HCl?
MA x (25.0 mL) = (0.100 M) x (40.0 mL)
MA = (40.0 mL) x (0.100 M) =
(25.0 mL)
0.160 M HCl

10. MAVA = MBVB B. Calculations Example (find conc.)
A 20.4 mL solution of KOH was completely neutralized by 48.5 mL of
0.150 M HNO3.
What is the concentration of the KOH?
(0.150 M) x (48.5 mL) = MB x (20.4 mL)
(0.150 M) x (48.5 mL) = MB =
(20.4 mL)
0.357 M KOH
