Acid-Base Titrations

Please login.

This is a 9 point assignment.

OBJECTIVES: After having completed this unit, students should be able to:

1. Define titration, titration curve, indicator, end-point, equivalence point and mid point (half-equivalence point).
2. Sketch a titration curve and identify various points on the curve.
   

3. Calculate the pH at various points along a titration curve for a strong acid with a strong base, strong base with a strong acid, weak acid with strong base or weak base with strong acid given the volume of the titrant and the concentration of the components.
4. Calculate the K_a for a weak acid  or K_b for a weak base from titration curve data.

14.7 Acid-Base Titrations

Questions 1-5 address general understanding of acid-base titration curves

Question 1:

Question 2:

Question 3:

Question 4:

Question 5:

Questions 6-9 cover pH calculations at various points of four titrations (not necessarily in the order below):

• strong acid with strong base
• weak acid with strong base
• strong base with strong acid
• weak base with strong acid.

Before starting each problem, you first need to recognize which type of titration it is.
