![**Question 21**
Report the largest pK for the weak acid whose titration curve is shown.
**Graph Description:**
The graph displays a titration curve of a weak acid. The x-axis is labeled with the concentration of hydroxide ions \([OH^-]\), and the y-axis is labeled with pH values. The curve begins at a pH below 7 and slopes upwards, showing an increase in pH as \([OH^-]\) increases. It has distinct regions, including a buffer region (where the curve flattens), indicating the pKa, where the weak acid is halfway neutralized. After this point, the curve shows a steeper increase in pH as more base is added.
Please report the largest pKa value observed in this titration curve.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F72a720b9-38b2-4beb-ae1b-56a99a6fccf3%2F2da7f986-acc9-46c2-b1f4-3e678a69735b%2Fv78qanh_processed.jpeg&w=3840&q=75)
