# Problem: A 25.0-mL sample of 0.125 M pyridine is titrated with 0.100 MHCl. Calculate the pH at 0 mL of added acid. Express your answer using two decimal places.

###### FREE Expert Solution

• Pyridine (C5H5N) → neutral amine → weak base

No acid added to the solution yet

• calculate pH of pyridine before titration (0 mL of acid is added) ###### Problem Details
