Question
**Titration pH Calculation Practice**
 
**Problem Statement:**

Calculate the pH at the equivalence point for the following titration:

- **Reactants:** 0.35 M HCOOH (Formic Acid) versus 0.35 M NaOH (Sodium Hydroxide)

**Instructions:**

1. Enter your answer in the provided box.
2. You have 3 attempts left to check your work.
3. Use appropriate references and materials as needed.

**Input Field:**
- pH = [Text Box]

**Resources:**
- **eBook**
- **Print**
- **References**
  
**Navigation:**
- Previous Page: [Prev] - 6 of 12
- Next Page: [Next]

**Note:**
- Ensure your calculations are accurate before submitting.
- Refer to your textbook for detailed procedures on calculating pH at the equivalence point.

**Example of a Titration Curve:**

_Typical Shape for Weak Acid-Strong Base Titration:_

1. Start: Low Initial pH due to weak acid (HCOOH).
2. Buffer Region: Gradual pH increase.
3. Equivalence Point: Sharp pH increase around 7 (Depends on the weak acid's strength and other factors).
4. After Equivalence: Flattens at the high pH due to excess strong base (NaOH).

Good luck with your calculations!
