In this lesson you will learn about the titration of a weak acid with a strong base as well as the titration of a weak base with a strong acid.
By the end of this lesson, students should be able to:
- calculate the pH for a weak acid-strong base titration using a stoichiometry step followed by an equilibrium step.
- calculate the pH for a weak acid-strong base titration after various volumes of titrant are added.
- explain mathematically the relationship between [H+} and Ka as well as pH and pKa at the halfway point in a titration.
- describe the differences between pH curves for strong and weak acids titrated with a strong base.
- outline the procedure for a weak base-strong acid titration after addition of titrant. That is before addition, before equivalence point, at equivalence point etc.
- summarize the characteristics of a weak base-strong acid titration curve.
Let’s examine the titration of a weak acid with a strong base in the video lesson below. Please take thorough notes as you watch it.
In the second part of this lesson below, you will learn about the titration of weak base with a strong acid. Please once again take notes as you watch the video lesson below.
