Explain how do you calculate pH for a titration of a weak base with a strong acid?
A sample which is having 25.0-mL of 0.100 M NH3 (Kb = 1.8 x10-5) is titrated with 0.100 M HCl solution. Determine the pH after the addition of 0.0 mL, 4.0 mL, 12.5 mL, 20.0 mL,24.0mL, 24.5 mL, 25.0 mL, 25.1 mL, 26.0 mL, 28.0mL, and 30.0mL.
