Unit 12: Acids and Bases

Section 4: Titration


Titration

Titration

  • Titration: The controlled addition and measurement of the amount of a solution of known concentration required to react completely with a measured amount of a solution of unknown concentration

    • - It provides a means to determine the concentration of an unknown solution.


Titration

Titration

  • End Point: Point in a titration at which an indicator changes color


Titration

  • Equivalence Point: Point where the two solutions used in a titration are present in chemically equivalent amounts

Sample Problem

In a titration 27.4 mL of 0.0154 M Ba(OH)2 is added to a 20.0 mL sample of HCl solution of unknown concentration until the equivalence point is reached. What is the molarity of the acid solution?

Ba(OH)2 + HCl  BaCl2 + H2O


Titration

Titration

Step One – Balancing

Ba(OH)2 + 2HCl BaCl2 + 2 H2O

Step Two – Given and Unknown

G: 27.4 mL of 0.0154 M Ba(OH)2 20.0 mL of HCl

U: # M of HCl

Step Three – Convert M to Mole

1L

1000 mL

0.0154 mol Ba(OH)2

1 L

27.4 mL

4.22 x 10-4 mol Ba(OH)2

Step Four – Convert Ba(OH)2 to mol HCl

2 mol HCL

1 mol Ba(OH)2

4.22 x 10-4 mol Ba(OH)2

8.44 x 10-4 mol HCl

Step Five – Use the mL of HCl to find concentration of HCl

8.44 x 10-4 mol HCl

20.0 mLHCl

1000 mL

1 L

4.22 x 10-2 m HCl

Sample Problem # 2

In a titration 20.0 mL of 5.0 x 10-3 M NaOH is added to a 10.0 mL sample of HCl until equivalence point is reached. What is the molarity of the acid solution?

NaOH + HCL  NaCl + H2O
