A `0.02 M` solution of phyridinium hydrochloride has `pH=3.44`. Calculate the ionization constant of pyridine.

Explanation

To calculate the ionization constant of pyridine (Kb) from the given information, we can follow these steps:

### Step 1: Understand the given information
We have a 0.02 M solution of pyridinium hydrochloride with a pH of 3.44. Pyridinium hydrochloride is a salt of a weak base (pyridine) and a strong acid (HCl).

### Step 2: Calculate the pOH
First, we need to find the pOH from the pH value:
\[
