Show equivalence point, 1/2 equivalence point, and pka on graph. Also, calculate the ka.

Transcribed Image Text:The image displays a graph titled "Volume vs pH," illustrating the relationship between the volume of base added and the resulting pH change. The x-axis represents the "Volume of base added (mL)" ranging from 0 to 30 mL, and the y-axis represents "pH" values ranging from 0 to 14.
**Graph Details:**
- The graph is a scatter plot with connected data points indicating a titration curve.
- As the volume of base added increases, the pH values start at around 2 and rise gradually.
- Initially, from 0 to about 10 mL, the pH increases slowly.
- A steep rise in pH occurs between approximately 15 to 25 mL of base added, indicating the equivalence point of the titration.
- After this sharp increase, the curve plateaus from about 25 to 30 mL, suggesting the solution has become a strong base with little further increase in pH.
This graph effectively demonstrates the titration of a strong acid with a strong base, highlighting the characteristic S-shape of a titration curve.
