To find the \( K_b \) for pyridine from the given information about pyridinium chloride, we can follow these steps: ### Step 1: Understand the Reaction Pyridinium chloride (\( C_5H_5NH^+Cl^- \)) dissociates in water to give pyridine (\( C_5H_5N \)) and hydronium ions (\( H_3O^+ \)): \[ C_5H_5NH^+ + H_2O \rightleftharpoons C_5H_5N + H_3O^+ \] ...
