Question
**Titration of Pyridine with HBr: pH Calculation** Calculate the pH for each case in the titration of 25.0 mL of 0.130 M pyridine, \( \text{C}_5\text{H}_5\text{N(aq)} \), with 0.130 M HBr(aq). The \( K_b \) of pyridine is \( 1.7 \times 10^{-9} \). 1. **Before Addition of Any HBr** - pH = [ ] 2. **After Addition of 12.5 mL of HBr** - pH = [ ] 3. **After Addition of 18.0 mL of HBr** - pH = [ ] 4. **After Addition of 25.0 mL of HBr** - pH = [ ] 5. **After Addition of 29.0 mL of HBr** - pH = [ ] *Note: This exercise involves the calculation of pH in the specific scenarios mentioned, using the base dissociation constant and volume details provided. Consider the reaction equations and stoichiometry for accurate calculation.* **Source:** McQuarrie, Rock, And Gallogly 4e - General Chemistry.
