Question

Transcribed Image Text:**Problem Statement:**
Determine the pH at 110.00 mL of titrant during the titration of 50.00 mL of 0.400 M B (a generic base with \( K_b = 7.58 \times 10^{-9} \)) using 0.200 M HNO₃.
**Instructions:**
- Enter your answer in scientific notation with 3 significant figures.
- Do not include any units in your answer.
- Do not round any intermediate calculations.
**Note:** Your answer is assumed to be reduced to the highest power possible.
**Answer:**
Your Answer: \(\_\_\_\_\) x 10 \(\_\_\_\_\)
**Explanation:**
In this problem, you will calculate the pH of a solution at a specific point in a titration process, involving a generic base and nitric acid. To solve this, you'll need to follow these steps:
1. **Calculate the moles of the base and acid.**
2. **Use the stoichiometry of the reaction to find the concentration of the conjugate acid/base formed.**
3. **Apply the Henderson-Hasselbalch equation or pH calculation method appropriate for the system.**
4. **Express the final pH in the required scientific notation.**
Ensure all intermediate steps are calculated without rounding, and provide the final answer with correct significant figures and notation.
![**Titration Problem: Finding pH at Equivalence Point**
In this exercise, we explore the concept of titration involving a weak base and a strong acid. Specifically, you need to determine the pH at the equivalence point in the titration of 50.00 mL of 0.400 M B, where B is a generic base with a base dissociation constant \( K_b = 4.70 \times 10^{-10} \), using 0.200 M HNO₃.
**Instructions for Submission:**
1. **Answer Format:**
- Provide your answer in scientific notation with 3 significant figures. For example, if your answer is 1.23 x 10^4, write it in the format provided below.
- Exclude any units from your answer.
2. **Calculation Guidelines:**
- Ensure all intermediate calculations are exact and without rounding.
3. **Note on Notation:**
- Your response is expected in the form reduced to the highest power possible.
