Determine the pH of a 0.25-M solution of pyridinium nitrate $\left({\text{C}}_{\text{5}}{\text{H}}_{\text{6}}{\text{NNO}}_{\text{3}}\right)\text{ at 25°C}$. [Pyridinium nitrate dissociates in water to give pyridinium ions $\left({\text{C}}_{\text{5}}{\text{H}}_{\text{6}}{\text{N}}^{\text{+}}\right)$, the conjugate acid of pyridinium (see Table 16.7), and nitrate ions $\left({\text{NO}}_3^{-}\right).]$
