**Titration of Pyridine with HBr: pH Calculations** Calculate the pH for each of the cases in the titration of 25.0 mL of 0.120 M pyridine, \( C_5H_5N(aq) \), with 0.120 M HBr(aq). The \( K_b \) of pyridine is \( 1.7 \times 10^{-9} \). 1. **Before addition of any HBr** - pH = [Enter calculation result] 2. **After addition of 12.5 mL of HBr** - pH = [Enter calculation result] 3. **After addition of 16.0 mL of HBr** - pH = [Enter calculation result] 4. **After addition of 25.0 mL of HBr** - pH = [Enter calculation result] 5. **After addition of 30.0 mL of HBr** - pH = [Enter calculation result] **Note:** This exercise is designed to apply knowledge of acid-base titration and equilibrium constants. Calculations involve determining the concentrations of species in solution after each addition and using equilibrium expressions to find the pH.

Dilute solutions of the same weak acid (pKą = 4.5) ranging in concentration from 2 × 10-6 M to 2 × 10-2 M (0.002 to 20 mM) are titrated with a strong base that is five times more concentrated than the acid. At low concentrations of a weak acid, how does the concentration of the acid affect the shape of the titration curve? The higher the concentration of the acid, the sharper the inflection at the equivalence point. The lower the concentration of the acid, the sharper the inflection at the equivalence point. The shape of the titration curve is the same, regardless of the acid's concentration. The shape of the titration curve depends only on the pKa of the acid, not its concentration.
