We are given being asked to determine the pH of a 25.0-mL sample of 0.125 M pyridine titrated with 20 mL of 0.100 M HCl.
Pyridine is a weak base and HCl is a strong acid. So, this is a weak base-strong acid titration
We are going to perform the following step:
Step 1: Determine initial concentrations
Step 2: Construct ICE Chart
Step 3: Calculate pH
A 25.0-mL sample of 0.125 M pyridine is titrated with 0.100 MHCl. Calculate the pH at 20 mL of added acid. Express your answer using two decimal places.
