## Calculation of Activity Coefficient for H⁺### Problem 1:**Measured pH of a 0.300 M HBr Solution**The measured pH of a 0.300 M HBr solution at 25 °C is 0.632. Calculate the activity coefficient for H⁺ in this solution.**Activity Coefficient \(\gamma_{H^+}\):**\[ \gamma_{H^+} = \]### Problem 2:**Measured pH of a 0.300 M HNO₃ Solution**The measured pH of a 0.300 M HNO₃ solution at 25 °C is 0.657. Calculate the activity coefficient for H⁺ in this solution.**Activity Coefficient \(\gamma_{H^+}\):**\[ \gamma_{H^+} = \]---### Explanation:To calculate the activity coefficient for \( H^+ \) in these solutions, follow these steps:1. **Determine the concentration of \( H^+ \) from the pH:** \[ [H^+] = 10^{-\text{pH}} \]2. **Calculate the activity coefficient \(\gamma_{H^+}\):** \[ \gamma_{H^+} = \frac{[H^+]_{\text{calc}}}{[H^+]_{\text{measured}}} \]Here,- \([H^+]_{\text{calc}}\) is the concentration of \( H^+ \) ions assuming full dissociation.- \([H^+]_{\text{measured}}\) is the concentration of \( H^+ \) ions derived from the measured pH. For a 0.300 M solution of a strong acid like HBr or HNO₃, we assume full dissociation:\[ \text{Initial} \ [H^+] = 0.300 \ M \]By substituting the measured pH values into the calculations, you can find \(\gamma_{H^+}\).---To provide a more comprehensive understanding, these will result in numerical answers when the pH measurements are plugged into the equations.
