Question- A 25.0-mL sample of a 0.090 M solution of aqueous trimethylamine is titrated with a 0.11 M solution of HCl. Calculate the pH of the solution after 10.0, 20.0, and 30.0 mL of acid have been added; pKb of (CH3)3N = 4.19 at 25*C
pH after 10.0 mL of acid have been added?
pH after 20.0 mL of acid have been added?
pH after 30.0 mL of acid have been added?
I am not able to get the correct answer please help me
