Question
**Titration pH Curve Analysis**

The provided graph 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 Description:
- **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 level, which ranges from 0 to 14.

- **Curve Characteristics:**
  - The initial pH is low, indicating an acidic solution.
  - As the base is added, the pH gradually increases.
  - A steep vertical rise occurs near the equivalence point, where the amounts of acid and base are stoichiometrically equivalent.
  - Following the equivalence point, the pH levels off, suggesting a basic solution.

### Titration Type:
1. The pH curve represents the titration of a **strong acid** with a **strong base**.

### Indicator Selection:
2. From the dropdown list, **Phenolphthalein** is chosen as the suitable indicator for identifying the endpoint of the titration.

### Indicator Color Chart:
The color change of various indicators across different pH levels is shown:

- **Malachite Green**: Changes from yellow to green between pH 0.2 and 1.8.
- **Thymol Blue**: Changes from red to yellow (pH 1.2 to 2.8) and from yellow to green to blue (pH 8.0 to 9.6).
- **Methyl Orange**: Changes from red to yellow between pH 3.2 and 4.4.
- **Bromocresol Green**: Changes from yellow to blue between pH 3.8 and 5.4.
- **Methyl Red**: Changes from red to yellow between pH 4.8 and 6.0.
- **Bromothymol Blue**: Changes from yellow to blue between pH 6.0 and 7.6.
- **Cresol Red**: Changes from yellow to red between pH 7.0 and 8.8.
- **Phenolphthalein**: Changes from colorless to pink between pH 8.2
