Question 1.
What is the initial pH of a 0.1 M solution of acetic acid?
Show hintHide hint
Use the dissociation constant for acetic acid (Ka).
Question 2.
Describe the buffer region in a titration.
Show hintHide hint
Think about how the pH changes when adding small amounts of titrant.
3Question 3.
What is true about the equivalence point in a weak acid-strong base titration?
- True
- False
Show hintHide hint
Remember the properties of acid-base combinations.
4Question 4.
What is the Henderson-Hasselbalch equation?
Show hintHide hint
Think about how the components of the equation relate to acid-base equilibrium.
Question 5.
A 0.1 M solution of a weak acid is titrated with a strong base. The pH is measured to be 4 at half-equivalence. What is the pKa of the acid?
Show hintHide hint
Remember the relation at half-equivalence.
Question 6.
In a titration of weak acid HA with strong base BOH, how would you determine the pH after the equivalence point?
Show hintHide hint
Focus on how the excess titrant influences the final pH.
