Question
![**Interpret pH titration plots.**
Answer the following about the titration plot shown below, involving a monoprotic acid and base.
**20 mL of 0.1M titrand titrated with 0.1M titrant. Data points at 1 mL increments.**
*Graph Description:*
The graph depicts a pH titration curve with pH on the vertical axis (ranging from 0 to 14) and the volume of titrant in milliliters (mL) on the horizontal axis (ranging from 0 to 50 mL). The plot illustrates the typical S-shaped curve of a titration.
- **Initial pH**: Starts at approximately 2.0, indicating an acidic solution.
- **Equivalence Point**: Around 20 mL, where a sharp rise in pH occurs from about 4.0 to 11.0, indicating the point of neutralization.
- **Final pH**: Levels off near 12.0, suggesting a basic solution after the equivalence point.
**Questions:**
(a) Is the species being titrated an acid or a base? [ ]
(b) Is the species being titrated strong or weak? [ ]
(c) What is the value of \( K_a \) (if a weak acid) or \( K_b \) (if a weak base) for the species being titrated? If the species is strong (100% dissociated), enter 999.
