![**Titration of a Monoprotic Acid with a Monoprotic Base**
The graph displayed illustrates the pH curve for the titration of 25 mL of a 0.1 M monoprotic acid solution with a 0.1 M solution of a monoprotic base.
**Graph Explanation:**
- **Axes**: The x-axis represents the volume of 0.1 M base added (in mL), ranging from 0 to 50 mL. The y-axis represents the pH, ranging from 0 to 14.
- **Curve Description**: Initially, the pH rises gradually as the base is added. Around 25 mL, there is a sharp increase in pH, indicating the equivalence point where the amount of acid equals the amount of base. After this point, the curve flattens again, showing that additional base does not significantly change the pH.
**Questions:**
1. **The pH curve represents the titration of a _weak_ acid with a _strong_ base.**
2. **Choose a suitable indicator for the endpoint of the titration from the following pulldown list: [Phenolphthalein].**
This pH curve is typical for the titration of a weak acid with a strong base, where the steep rise in pH indicates the transition through the equivalence point. Phenolphthalein is a suitable indicator for this type of titration due to its color change in the basic pH range.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbea8501a-47cf-43c6-9fd0-955ec556d935%2Fc231b728-8d25-48cd-8c5b-2a2cd0af7f33%2F9fbdecc_processed.png&w=3840&q=75)
