A: 48.0 mL volume of 0.25 M HBr is titrated with 0.50 M KOH. Calculate the pH after addition of 24.0 mL of KOH at 25 âC B: Consider the titration of 50.0 mL of 0.20 M NH3 (Kb=1.8Ã10â5) with 0.20 M HNO3. Calculate the pH after addition of 50.0 mL of the titrant at 25 âC.
C: A 30.0-mL volume of 0.50 M CH3COOH (Ka=1.8Ã10â5) was titrated with 0.50 M NaOH. Calculate the pH after addition of 30.0 mL of NaOH at 25 âC
